Upanishads Taittiriya Upanishad’s hymn 1.9.1 emphasizes the central importance of
Svadhyaya in one’s pursuit of Reality (
Ṛta), Truth (
Satya), Self-restraint (Damah), Perseverance (
Tapas), Tranquility and Inner Peace (Samas), Relationships with others, family, guests (Praja, Prajana, Manush, Atithi) and all Rituals (Agnaya, Agnihotram). Taittiriya Upanishad, however, adds in verse 1.9.1, that along with the virtue of ''
process of learning, one must teach and share (pravacana'') what one learns. In verse 1.11.1, the final chapter in the education of a student, the Taittiriya Upanishad reminds, One of the earliest mention of Svādhyāya is found in
Taittiriya Aranyaka 2.15: "" ("svādhyāya must be practiced"). Śatpath Brāhmana also repeats it.
Chandogya Upanishad verse 4.16.1-2 recommends both silent (
mānas) and vocal (
vāchika) types of svādhyāya.
Other scriptures Patanjali's
Yogasutra, in verse II.44, recommends
Svadhyaya as follows Vishnu Smriti's verse 22.92, states that "human body is cleansed by water, the mind is cleansed by truth, the soul by self-study and meditation, while understanding is cleansed by knowledge". Vasistha
Dharmasastra verses 27.1 through 27.7 states that
Svadhyaya helps an individual understand and overcome his past. Apastamba Dharmasutra 1.4.12.1 states
Svadhyaya is a form of
Tapas. This view is shared by Baudhayana Dharmasastra in verses 4.1.29 to 4.1.30, which adds that ‘‘svadhyaya is a means of getting past one’s past mistakes and any guilt”. Baudhayana Dharmasastra describes ‘‘Svadhyaya’’, in verse 2.6.11, as the path to
Brahman (Highest Reality, Universal Spirit, Eternal Self).
Svadhyaya is mentioned a second time in
Bhagavad Gita verse 17.15 as a component of the discipline of one's speech by which, states the verse, " speak words that are truthful, kind, helpful, and elevates those who hear it". ==Svadhyaya as a historical practice==
