To trust a stranger without investigation invites troubles so endless that even descendants must endure them. To rust a man who has not been tested and to suspect a man who has proven trustworthy lead alike to endless ills.
Scholars who incessantly contemplate acquiring strength and knowledge should also consider it their moral duty to impart knowledge to the ignorant, so that they can develop their mental faculties. This would automatically lead to the latter’s self-development and spiritual progress.
If you desire to be pure, have firm faith, and slowly go on with your devotional practices without wasting your energy in useless scriptural discussions and arguments.
Blessed with a priceless life, why should I not fit it with compassion for all beings?
