In plain words
Holding that “Ahiṃsā is the highest Dharma” and doing no harm to any being in thought, word or deed, ‘Gautama Buddha’ adorned the seat of the teacher. To keep all these Dharmas with discipline and as prescribed is itself a tapas in life. Of the three instruments, the Manas comes first. It must keep far from impulses, agitations and cravings. These qualities are natural to the Manas. Lust, anger, greed, delusion, pride and envy are the impulses that arise in the Manas. They are man's inner enemies. Of these the first two are lust and anger. The other four qualities live by following these. So it is those who bring the first two under control and do sādhana who have kept their humanness. What teaches such Vidyā is “Brahmavidyā”.
