Romanization of Sanskrit

The Bhagavad Gita (/ˈbʌɡəvəd ˈɡiːtɑː/; Sanskrit: भगवद्गीता, IPA: [ˌbʱɐɡɐʋɐd ˈɡiːtɑː], romanized: bhagavad-gītā, lit. 'God's song'), often referred to as the Gita (IAST: gītā), is a Hindu scripture, likely composed in the second or first century BCE, which forms part of the epic poem Mahabharata. The Gita is a synthesis of various strands of Indian religious thought, including the Vedic concept of dharma (duty, rightful action); Sankhya-based yoga and jnana (knowledge); and bhakti (devotion). Among the Hindu traditions, the Gita holds a unique pan-Hindu influence as the most prominent sacred text and is a central text in the Vedanta and Vaishnava traditions.

While traditionally attributed to the sage Veda Vyasa, the Gita is historiographically regarded as a composite work by multiple authors. Incorporating teachings from the Upanishads and the samkhya yoga philosophy, the Gita is set in a narrative framework of dialogue between the Pandava prince Arjuna and his charioteer guide Krishna, an avatar of Vishnu, at the onset of the Kurukshetra War.

Purushartha (Sanskrit: पुरुषार्थ, romanized: Puruṣārtha; pronounced [pu.ɾu.ʂɑːɾ.tʰɐ]) literally means "object(ive) of men". It is a key concept in Hinduism, and refers to the four proper goals or aims of a human life. The four puruṣārthas are Dharma (righteousness, moral values), Artha (prosperity, economic values), Kama (pleasure, love, psychological values) and Moksha (liberation, spiritual values, self-realization).

All four Purusharthas are important, but in cases of conflict, Dharma is considered more important than Artha or Kama in Hindu philosophy. Moksha is considered the ultimate goal of human life. At the same time, this is not a consensus among all Hindus, and many have different interpretations of the hierarchy, and even as to whether one should exist.

Puja (Sanskrit: पूजा, romanized: pūjā) is a worship ritual performed by Hindus to offer devotional homage and prayer to one or more deities, to host and honour a guest, or to spiritually celebrate an event. It may honour or celebrate the presence of special guests, or their memories after they die. The word puja is roughly translated into English as 'reverence, honour, homage, adoration, or worship'. Puja, the loving offering of light, flowers, and water or food to the divine, is the essential ritual of Hinduism. For the worshipper, the divine is visible in the image, and the divinity sees the worshipper. The interaction between human and deity, between human and guru, is called a Darshanam.

In Hindu practice, puja is done on a variety of occasions, frequencies, and settings. It may include a daily puja done in the home, or occasional temple ceremonies and annual festivals. In other cases, puja is held to mark a few lifetime events such as the birth of a baby, house entering ceremony or grihapravesh, first rice-eating ceremony or annaprasana, wedding, sacred thread ceremony or upanayana ceremony for the Brahmins or to begin a new venture. The two main areas where puja is performed are in the home and at temples to mark certain stages of life, events or some festivals such as Durga Puja, Kali Puja, Janmashtami, and Lakshmi Puja. Puja is not mandatory in Hinduism. It may be a routine daily affair for some Hindus, a periodic ritual for some, and rare for other Hindus. In some temples, various pujas may be performed daily at various times of the day; in other temples, they may be occasional.

Shaivism (/ˈʃaɪvɪzəm/; Sanskrit: शैवसंप्रदायः, romanized: Śaivasampradāyaḥ) is one of the major Hindu religious traditions, which worships Shiva as the supreme being. It is the second-largest Hindu sect, after Vaishnavism, constituting about 385 million Hindus, found widely across South Asia predominantly in India, Sri Lanka, and Nepal. The followers of Shaivism are called Shaivas or Shaivites.

According to Chakravarti, Shaivism developed as an amalgam of pre-Aryan religions and traditions, Vedic Rudra, and post-Vedic traditions, accommodating local traditions and Yoga, puja and bhakti. According to Bisschop, early shaivism is rooted in the worship of the vedic deity Rudra. The earliest evidence for sectarian Rudra-Shiva worship appears with the Pasupata (early CE), possibly owing to the Hindu synthesis, when many local traditions were aligned with the Vedic-Brahmanical fold. The Pāśupata movement rapidly expanded throughout North India, giving rise to different forms of Shaivism, which led to the emergence of various tantric traditions. Both devotional and monistic Shaivism became popular in the 1st millennium CE, rapidly becoming the dominant religious tradition of many Hindu kingdoms. It arrived in Southeast Asia shortly thereafter, leading to the construction of thousands of Shaiva temples on the islands of Indonesia as well as Cambodia and Vietnam, co-evolving with Buddhism in these regions.

Vaishnavism (Sanskrit: वैष्णवसम्प्रदायः, romanized: Vaiṣṇavasampradāyaḥ), also called Vishnuism, is one of the major Hindu religious traditions, that considers Vishnu as the supreme being leading all other Hindu deities, that is, Mahavishnu. It is one of the major Hindu denominations along with Shaivism, Shaktism, and Smartism. Its followers are called Vaishnavites or Vaishnavas (IAST: Vaiṣṇava), and it includes sub-sects like Krishnaism and Ramaism, which consider Krishna and Rama as the supreme beings respectively. According to a 2020 estimate by The World Religion Database (WRD), hosted at Boston University's Institute on Culture, Religion and World Affairs (CURA), Vaishnavism is the largest Hindu sect, constituting about 399 million Hindus.

The ancient emergence of Vaishnavism is unclear, and broadly hypothesized as a fusion of various regional non-Vedic religions with worship of Vishnu. It is considered a merger of several popular non-Vedic theistic traditions, particularly the Bhagavata cults of Vāsudeva-Krishna and Gopala-Krishna, as well as Narayana, developed in the 7th to 4th century BCE. It was integrated with the Vedic God Vishnu in the early centuries CE, and finalized as Vaishnavism, when it developed the avatar doctrine, wherein the various non-Vedic deities are revered as distinct incarnations of the supreme God Vishnu. Narayana, Hari, Rama, Krishna, Kalki, Perumal, Shrinathji, Vithoba, Venkateswara, Guruvayurappan, Ranganatha, Jagannath, Badrinath and Muktinath are revered as forms or avatars of Vishnu, all seen as different aspects of the same supreme being.

Shaktism (Sanskrit: शाक्तसम्प्रदायः, romanized: Śāktasampradāyaḥ) is a major Hindu denomination in which the ultimate reality is considered as Adi Parashakti.

In Shaktism, the divine feminine energy, Shakti, is revered as the supreme power and is personified as the Mahadevi (Great Goddess), who manifests in numerous forms, with each form having distinct functions and unique attributes. The most prominently worshiped goddesses include Durga, the fierce protector who vanquishes evil and restores cosmic order; Parvati, the gentle yet powerful mother goddess of fertility, devotion, and spiritual wisdom; and Kali, the primal force of time and transformation. Additionally, Shaktism reveres a broader pantheon, including goddesses like Saraswati, the goddess of knowledge and arts; Lakshmi, the goddess of wealth and prosperity; and Tripura Sundari, the goddess of beauty and grace. Also honoured are the various Gramadevata, local village guardian deities, who protect and bless their communities. Following the decline of Buddhism in India, elements of Hindu and Buddhist goddess worship gradually merged, culminating in the emergence of the Mahavidya, a revered group of ten fierce and esoteric goddesses central to the tantric traditions within Shaktism.

Samkhya or Sankhya (/ˈsɑːŋkjə/; Sanskrit: सांख्य, romanized: Sāṅkhya) is a dualistic orthodox school of Hindu philosophy. It views reality as composed of two independent principles, Puruṣa ('consciousness' or spirit) and Prakṛti (nature or matter, including the human mind and emotions).

Puruṣa is the witness-consciousness. It is absolute, independent, free, beyond perception, above any experience by mind or senses, and impossible to describe in words.

In Buddhism, the Four Noble Truths (Sanskrit: चत्वार्यार्यसत्यान, romanized: catvāryāryasatyāni; Pali: cattāri ariyasaccāni; "The Four arya satya") are "the truths of the noble one (the Buddha)," a statement of how things really are when they are seen correctly. The four truths are

• dukkha (not being at ease, 'suffering', from dush-stha, standing unstable). Dukkha is an innate characteristic of transient existence; nothing is forever, this is painful;
• samudaya (origin, arising, combination; 'cause'): together with this transient world and its pain, there is also thirst (desire, longing, craving) for and attachment to this transient, unsatisfactory existence;
• nirodha (cessation, ending, confinement): the attachment to this transient world and its pain can be severed or contained by the confinement or letting go of this craving;
• marga (road, path, way): the Noble Eightfold Path is the path leading to the confinement of this desire and attachment, and the release from dukkha.

The four truths appear in many grammatical forms in the ancient Buddhist texts, and are traditionally identified as the first teaching given by the Buddha. While often called one of the most important teachings in Buddhism, they have both a symbolic and a propositional function. Symbolically, they represent the awakening and liberation of the Buddha, and of the potential for his followers to reach the same liberation and freedom that he did. As propositions, the Four Truths are a conceptual framework that appear in the Pali canon and early Hybrid Sanskrit Buddhist scriptures, as a part of the broader "network of teachings" (the "dhamma matrix"), which have to be taken together. They provide a conceptual framework for introducing and explaining Buddhist thought, which has to be personally understood or "experienced".

The Noble Eightfold Path (Sanskrit: आर्याष्टाङ्गमार्ग, romanized: āryāṣṭāṅgamārga) or Eight Right Paths (Sanskrit: अष्टसम्यङ्मार्ग, romanized: aṣṭasamyaṅmārga) is an early summary of the path of Buddhist practices leading to liberation from samsara, the painful cycle of rebirth, in the form of nirvana.

The Eightfold Path consists of eight practices: right view, right resolve, right speech, right conduct, right livelihood, right effort, right mindfulness, and right samadhi ('meditative absorption or union'; alternatively, equanimous meditative awareness).

Mahavishnu (Sanskrit: महाविष्णु, romanized: Mahāviṣṇu, lit. 'Great Vishnu') is an aspect of Vishnu, the principal deity in Vaishnavism. In his capacity as Mahavishnu, the deity is known as the Supreme Purusha, the absolute protector and sustainer of the universe, the one who is beyond human comprehension, and all attributes.

The term Mahavishnu refers to the absolute truth, Brahman (impersonal invisible aspect) then as Paramatma (Aspect beyond the understanding of human soul), and finally as Sarvatma (incarnating for bringing perfection). Bhakti (loving devotion) is offered to Sarvatman (Krishna or Rama avatars or incarnations of Vishnu, Narayana bringing both peace and perfection of the living beings). In this way, bhakti surpasses even yoga, which is aimed at the Supersoul, Paramatman. Mahavishnu is the Supersoul of all living beings (jivatmas) in all material universes. Karanodaksayi Vishnu is understood to be Sankarsana (form) of the Chatur-vyuha of Narayaņa. It is also often used interchangeably with Vishnu to indicate reverence, as the prefix "Maha" in Vishnu indicates the greatness and the vastness of Narayana. All the deities that bear material form like Shiva and Brahma are considered as a grain of sand in the ocean of Mahavishnu's Vishvarupam.
