Guru in the context of "Guru Gobind Singh"

In the Czech Republic, 47.8% of the population is irreligious (atheist, agnostic or other irreligious life stances), while 21.3% of the population are believers. The religious identity of the country has changed drastically since the first half of the 20th century, when more than 90% of Czechs were Christians. As of 2021, 11.7% of the population identified with Christianity (9.3% identifying with Catholicism and 2.4% with all other Christian denominations); 10.8% identified with other religious identities or beliefs. According to sociologist Jan Spousta, not all the irreligious people are atheists; indeed, since the late 20th century there has been an increasing distancing from both Christian dogmatism and atheism, and at the same time ideas and non-institutional models similar to those of Eastern religions have become widespread through movements started by various gurus, and hermetic and mystical paths.

Sikhism is an Indian religion and philosophy that originated in the Punjab region of the Indian subcontinent around the end of the 15th century CE. It is one of the most recently founded major religions and is followed by 25–30 million adherents, known as Sikhs.

Sikhism developed from the spiritual teachings of Guru Nanak (1469–1539), the faith's first guru, and the nine Sikh gurus who succeeded him. The tenth guru, Guru Gobind Singh (1666–1708), named the Guru Granth Sahib, which is the central religious scripture in Sikhism, as his successor. This brought the line of human gurus to a close. Sikhs regard the Guru Granth Sahib as the 11th and eternally living guru.

Sampradaya (Sanskrit: सम्प्रदाय; IAST: Saṃpradāya), in Indian-origin religions, namely Hinduism, Buddhism, Jainism, and Sikhism, can be translated as 'tradition', 'spiritual lineage', 'sect', or 'religious system'. To ensure continuity and transmission of dharma, various sampradayas have the Guru-shishya parampara in which a parampara or lineage of successive gurus (masters) and shishyas (disciples) serves as a spiritual channel and provides a reliable network of relationships that lends stability to a religious identity. Shramana is vedic term for seeker or shishya. Identification with and followership of sampradayas is not static, as sampradayas allows flexibility where one can leave one sampradaya and enter another or practice religious syncretism by simultaneously following more than one sampradaya. Samparda is a Punjabi language term, used in Sikhism, for sampradayas.

Bhakti (Sanskrit: भक्ति; Pali: bhatti) is a concept common in Indian religions which means attachment, fondness for, devotion to, trust, homage, worship, piety, faith, or love. In Indian religions, it may refer to loving devotion for a personal God (like Krishna or Devi), a formless ultimate reality (like Nirguna Brahman or the Sikh God) or an enlightened being (like a Buddha, a bodhisattva, or a guru). Bhakti is often a deeply emotional devotion based on a relationship between a devotee and the object of devotion. A devotee is a bhakta or bhakt.

One of the earliest appearances of the concept is found in the early Buddhist Theragatha (Verses of the Elders) through the term bhatti. Early texts such as the Shvetashvatara Upanishad and the Bhagavad Gita, describe bhakti as contemplating God as a form of yoga.

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.

Vajrayāna (Sanskrit: वज्रयान, lit. 'Diamond Vehicle or Thunderbolt Vehicle'), otherwise known as Mantrayāna ("Mantra Vehicle"), Guhyamantrayāna ("Secret Mantra Vehicle"), Tantrayāna ("Tantra Vehicle"), Indo-Tibetan Buddhism, Tantric Buddhism, and Esoteric Buddhism, is a Mahāyāna Buddhist tradition that emphasizes esoteric practices and rituals aimed at rapid spiritual awakening. Emerging between the 5th and 7th centuries CE in medieval India, Vajrayāna Buddhism incorporates a range of techniques, including the use of mantras (sacred sounds), dhāraṇīs (mnemonic codes), mudrās (symbolic hand gestures), mandalās (spiritual diagrams), and the visualization of deities and Buddhas. These practices are designed to transform ordinary experiences into spiritual paths toward enlightenment and liberation, often by engaging with aspects of desire and aversion in a ritualized context.

A distinctive feature of Vajrayāna Buddhism is its emphasis on esoteric transmission, where teachings are passed directly from teacher (guru or vajrācārya) to student through initiation ceremonies. Tradition asserts that these teachings have been passed down through an unbroken lineage going back to the historical Buddha (c. the 5th century BCE), sometimes via other Buddhas or bodhisattvas (e.g., Vajrapani). This lineage-based transmission ensures the preservation of the purity and effectiveness of the teachings. Practitioners often engage in deity yoga, a meditative practice where one visualizes oneself as a deity embodying enlightened qualities to transform one's perception of reality. The tradition also acknowledges the role of feminine energy, venerating female Buddhas and ḍākiṇīs (spiritual beings), and sometimes incorporates practices that challenge conventional norms to transcend dualistic thinking.

Avatar (Sanskrit: अवतार, IAST: Avatāra; pronounced [ɐʋɐt̪aːɾɐ]) is a concept within Hinduism that in Sanskrit literally means 'descent'. It signifies the material appearance or incarnation of a powerful deity, or spirit on Earth, including in human form. The relative verb to "alight, to make one's appearance" is sometimes used to refer to any guru or revered human being.

The word avatar does not appear in the Vedic literature; however, it appears in developed forms in post-Vedic literature, and as a noun particularly in the Puranic literature after the 6th century CE. Despite that, the concept of an avatar is compatible with the content of the Vedic literature like the Upanishads as it is symbolic imagery of the Saguna Brahman concept in the philosophy of Hinduism. The Rigveda describes Indra as endowed with a mysterious power of assuming any form at will. The Bhagavad Gita expounds the doctrine of Avatara but with terms other than avatar.

Agastya was a revered Indian sage of Hinduism. In the Indian tradition, he is a noted recluse and an influential scholar in diverse languages of the Indian subcontinent. He is regarded in some traditions to be a Chiranjivi. He and his wife Lopamudra are the celebrated authors of hymns 1.165 to 1.191 in the Sanskrit text Rigveda and other Vedic literature.

Agastya is considered to be the father of Siddha medicine. Agastya appears in numerous itihasas and Puranas including the major Ramayana and Mahabharata. He is one of the seven most revered rishis (the Saptarishi) in the Vedic texts, and is revered as one of the Tamil Siddhar in the Shaivism tradition, who invented an early grammar of the Old Tamil language, Agattiyam, playing a pioneering role in the development of Tampraparniyan medicine and spirituality at Saiva centres in proto-era Sri Lanka and South India. He is also revered in the Puranic literature of Shaktism and Vaishnavism. He is one of the Indian sages found in ancient sculpture and reliefs in Hindu temples of South Asia, and Southeast Asia such as in the early medieval era Shaiva temples on Java Indonesia. He is the principal figure and Guru in the ancient Javanese language text Agastyaparva, whose 11th-century version survives.

Pehlwani, also known as Kushti, is a form of wrestling contested in the Indian subcontinent. It was developed in the Mughal Empire by combining Persian Koshti pahlevani with influences from native Indian Malla-yuddha. The words pehlwani and kushti derive from the Persian terms pahlavani (heroic) and koshti (wrestling, lit. killing) respectively, meaning Heroic wrestling. A practitioner of this sport is referred to as a pehlwan (Persian word for hero) while teachers are known as ustad (Persian word for teacher or master) or guru.

One of the most famous practitioners of Pehlwani was The Great Gama (Ghulam Mohammad Baksh Butt), who is considered one of the greatest wrestlers of all time. Kodi Rammurthy Naidu was another example. Brahmdev Mishra is another example of an Indian wrestler who was known for his technique and physique not only in India but all over the world. Pehlwani is one of the sports that influenced catch wrestling, which in turn partially inspired folkstyle wrestling, freestyle wrestling, and mixed martial arts (MMA).
