Satya
सत्य (satya)
Truthfulness - alignment of speech and life with what is, restrained by ahimsa from becoming a weapon.
Satya derives from sat, that which is. Truthfulness in this tradition is thus more than accuracy: it is loyalty to reality, a refusal to prop up comfortable fictions - beginning with one's own.
The classical commentaries order the restraints deliberately: satya stands second, after ahimsa, and is bound by it. Truth spoken to wound fails the earlier vow; the honest tongue is not licensed to be a blade. Where truth and kindness seem to conflict, the tradition asks for the harder synthesis - true speech, kindly said, at the right time, or else silence.
A workable daily form: notice the small exaggerations, the strategic omissions, the flattery. Not to prosecute them - just to notice. Speech cleans up quickly under honest observation.
