Satya in the context of Yoga

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 Five Vows of Jainism include the mahāvratas (major vows) and aṇuvratas (minor vows). Jain ethical code prescribes two dharmas or rules of conduct. One for those who wish to become ascetic and another for the śrāvaka (householders). Five fundamental vows are prescribed for both votaries. These vows are observed by śrāvakas (householders) partially and are termed as anuvratas (small vows). Ascetics observe these fives vows more strictly and therefore observe complete abstinence. These five vows are:

• Ahiṃsā (Non-violence)
• Satya (Truth)
• Asteya (Non-stealing)
• Brahmacharya (Chastity)
• Aparigraha (Non-possession)

According to the Jain text Puruşārthasiddhyupāya:

The Mahāvākyas (sing.: mahāvākyam, महावाक्यम्; plural: mahāvākyāni, महावाक्यानि) are "The Great Sayings" of the Upanishads, with mahā meaning great and vākya, a sentence. The Mahāvākyas are traditionally considered to be four in number, though actually five are prominent in the post-Vedic literature:

1. Tat Tvam Asi (तत् त्वम् असि) – literally translated as "That Thou Art" ("That is you" or "You are that"), appears in Chandogya Upanishad 6.8.7 of the Sama Veda, with tat in Ch.U. 6.8.7 referring to *sat, "the Existent," and contextually understood as "That's how [thus] you are," with tat in Ch.U. 6.12.3 referring to "the very nature of all existence as permeated by [the finest essence]."
2. Ahaṁ Brahmāsmi (अहं ब्रह्मास्मि) - "I am Brahman", or "I am absolute" (Brihadaranyaka Upanishad 1.4.10 of the Yajur Veda)
3. Prajñānaṁ Brahma (प्रज्ञानं ब्रह्म) - "Prajñāna is Brahman", or "Brahman is Prajñāna" (Aitareya Upanishad 3.3 of the Rig Veda)
4. Ayam Ātmā Brahma (अयम् आत्मा ब्रह्म) - "This Self (Atman) is Brahman" (Mandukya Upanishad 1.2 of the Atharva Veda)
5. Sarvaṃ Khalvidaṃ Brahma - "All this indeed is Brahman"(Chāndogya Upaniṣad 3.14.1)

Mahāvākyas are instrumental in Advaita Vedanta, as they are regarded as valid scriptural statements that reveal the self (ātmán), which appears as a separate individual existence (jīva), is, in essence, non-different (not two-ness) from Brahman, which, according to Advaita, is nirguna. In contrast, these statements are less prominent in most other Hindu traditions, which emphasize a qualified or dualistic relationship between the self and Brahman, whom they regard as saguna, often identified with Vishnu, Shiva, Shakti, etc.

The Buddhist doctrine of the two truths (Sanskrit: dvasatya, Wylie: bden pa gnyis) differentiates between two levels of satya (Sanskrit; Pāli: sacca; meaning "truth" or "reality") in the teaching of Śākyamuni Buddha: the "conventional" or "provisional" (saṁvṛti) truth, and the "absolute" or "ultimate" (paramārtha) truth.

The exact meaning varies between the various Buddhist schools and traditions. The best known interpretation is from the Mādhyamaka school of Mahāyāna Buddhism, whose founder was the 3rd-century Indian Buddhist monk and philosopher Nāgārjuna. For Nāgārjuna, the two truths are epistemological truths. The phenomenal world is accorded a provisional existence. The character of the phenomenal world is declared to be neither real nor unreal, but logically indeterminable. Ultimately, all phenomena are empty (śūnyatā) of an inherent self or essence due to the non-existence of the self (anātman), but temporarily exist depending on other phenomena (pratītya-samutpāda).

Ratri (Sanskrit: रात्रि, lit. 'night', IAST: Rātri; also referred to as Nisha), is a Vedic goddess in Hinduism. She is the personification of the night. The majority of references to Ratri are found in Rigveda and she is described as the sister of Ushas, the personification of dawn. Together with Ushas, she is referred to as a powerful mother and strengthener of vital power. She represents cyclic rhythmic patterns of the cosmos. Her physical appearance isn't explicitly mentioned, but she is described as a beautiful maiden.

One hymn in the Rigveda and five hymns in the Atharvaveda are dedicated to her. In later Tantric texts she occupies an important position. She is associated with Ushas, Indra, Rta, Satya in Rigveda, whereas in Atharvaveda she is associated with Surya. The Brahmanas and the Sutra literature often mention Ratri.
