Svadhyaya
स्वाध्याय (svādhyāya)
Self-study - the twin discipline of studying the texts and studying the one who is reading them.
Svadhyaya folds two meanings into one word: study of the sacred texts, and study of oneself - sva, one's own, adhyaya, going into. The tradition refuses to separate them. A text read without self-observation becomes trivia; a self examined without any mirror becomes a hall of flattering echoes.
Classically this meant recitation of one's portion of the Veda. More broadly it names a way of reading in which the reader is also the subject: noticing what a verse provokes, where resistance rises, which teachings one conveniently forgets.
A practical form: keep one text going slowly - a few verses, returned to daily - and one notebook beside it. The notebook is not for summarising the text. It is for recording what the text found in you.
