Devotees in the path of work perform action, only with body, mind, senses, and intellect, forsaking attachment, for the purification of the heart. Lord Krishna
The evil-doer mourns in this world, and he mourns in the next; he mourns in both. He mourns and suffers when he sees the evil of his own work. Buddha
Endued with this evenness of mind, one frees oneself in this life, alike from vice and virtue. Devote thyself, therefore, to this Yoga. Yoga is the very dexterity of work. Lord Krishna
