ब्रह्मविदाप्नोति परम् । तदेषाऽभ्युक्ता । सत्यं ज्ञानमनन्तं ब्रह्म

Never err from Truth,

Never err from Dharma,

Never neglect your well-being,

Never neglect your health,

Never neglect your prosperity,

Never neglect Svādhyāya (study of oneself) and Pravacana (exposition of Vedas).

— Taittirĩya Upanishad, I.11.1^[41][42]

Virtue is its own reward

knowledge is a virtue. Man cannot be wise except by knowing, even if it is only by knowing that he doesn't know anything "worth knowing"

- Socrates
