Satya is a Sanskrit word loosely translated as truth, essence. It also refers to a virtue in Indian religions, referring to being truthful in one's thought, speech and action. In Yoga, satya'' is one of five yamas, the virtuous restraint from falsehood and distortion of reality in one's expressions and actions.
Etymology
In the Vedas and later sutras, the meaning of the word satya evolves into an ethical concept about truthfulness and is considered an important virtue. It means being true and consistent with reality in one's thought, speech and action. A related concept, sattva, also derived from "sat", means true essence, nature, spiritual essence, character. Sattva is also a guṇa, a psychology concept particularly in the Samkhyaschool of philosophy, where it means goodness, purity, clean, positive, one that advances good true nature of self. Satya has cognates in a number of diverse Indo-European languages, including the word "sooth" and "sin" in English, "istina" in Russian, "sand" - truthful in Danish/"sann" in Swedish, and "haithya" in Avestan, the liturgical language of Zoroastrianism..
Hinduism
Vedic literature
Satya is a central theme in the Vedas. It is equated with and considered necessary to the concept Ṛta – that which is properly joined, order, rule, nature, balance, harmony. Ṛta results from Satya in the Vedas, states Holdrege, as it regulates and enables the operation of the universe and everything within it. Satya is considered essential, and without it, the universe and reality falls apart, cannot function. In Rigveda, opposed to rita and satya are anrita and asatya. Truth and truthfulness is considered as a form of reverence for the divine, while falsehood a form of sin. Satya includes action and speech that is factual, real, true and reverent to Ṛta in Book 1, 4, 6, 7, 9 and 10 of Rigveda. However, Satya isn't merely about one's past that is in context in the Vedas, it has one's current and one's future contexts as well. De Nicolás states, that in Rigveda, "Satya is the modality of acting inthe world of Sat, as the truth to be built, formed or established".
Upanishads
Satya is a widely discussed concept in various Upanishads, including the Brihadaranyaka Upanishad where satya is called the means to Brahman, as well as Brahman. In hymn 1.4.14 of Brihadaranyaka Upanishad, Satya is equated to Dharma, as Taittiriya Upanishad's hymn 11.11 states, "Speak the Satya, conduct yourself according to the Dharma ". Truth is sought, praised in the hymns of Upanishads, held as one that ultimately, always prevails. The Mundaka Upanishad, for example, states in Book 3, Chapter 1, Sandilya Upanishad of Atharvanaveda, in Chapter 1, includes ten forbearances as virtues, in its exposition of Yoga. It defines Satya as "the speaking of the truth that conduces to the well being of creatures, through the actions of one's mind, speech or body." Deussen states that Satya is described in the major Upanishads with two layers of meanings - one as empirical truth about reality, another as abstract truth about universal principle, being and the unchanging. Both these ideas are explained in early Upanishads, composed before 500 BC, by variously breaking the word satya or satyam into two or three syllables. In later Upanishads, the ideas evolve and transcend into satya as truth, and Brahman as the Being, Be-ness, real Self, the eternal.
Epics
The Shanti Parva of the Mahabharata states, "The righteous hold that forgiveness, truth, sincerity and compassion are the foremost. Truth is the essence of the Vedas." The Epic repeatedly emphasizes that Satya is a basic virtue, because everything and everyone depends on and relies on Satya.
Sutras
In the Yoga Sutras of Patanjali, it is written, “When one is firmly established in speaking truth, the fruits of action become subservient to him." In Yoga sutra, Satya is one of the five yamas, or virtuous restraints, along with ahimsa ; asteya ; brahmacharya ; and aparigraha. Patanjali considers satya as a restraint from falsehood in one's action, words, or feelings / thoughts. In Patanjali's teachings, one may not always know the truth or the whole truth, but one knows if one is creating, sustaining or expressing falsehood, exaggeration, distortion, fabrication or deception. Satya is, in Patanjali's Yoga, the virtue of restraint from such falsehood, either through silence or through stating the truth without any form of distortion.
Jainism
Satya is one of the five vows prescribed in Jain Agamas. Satya was also preached by Mahavira. According to Jainism, not to lie or speak what is not commendable. The underlying cause of falsehood is passion and therefore, it is said to cause hiṃsā. According to the Jain textSarvārthasiddhi: "that which causes pain and suffering to the living is not commendable, whether it refers to actual facts or not". According to Jain text, Puruşārthasiddhyupāya:
Buddhism
The term satya is translated in English as "reality" or "truth." In terms of the Four Noble Truths, the Pali can be written as sacca, tatha, anannatatha and dhamma. 'The Four Noble Truths' are the briefest synthesis of the entire teaching of Buddhism, since all those manifold doctrines of the threefold Pali canon are, without any exception, included therein. They are the truth of suffering, of the origin of suffering, of the extinction of suffering, and of the Noble Eightfold Path leading to the extinction of suffering.
