Satya - Truthfulness
Truth as the foundation of spiritual life.
Satya (truth) is supreme. To live in alignment with truth is to live in alignment with Brahman, which is Truth itself. Truthfulness in thought, word, and deed purifies the mind.
Truth alone triumphs, not untruth.
This verse is India's national motto: Satyameva Jayate.
