The Blessed Lord said: Oh son of Pṛthā! Neither here nor in the hereafter is there destruction for him. No doer of good ever perishes or reaches an adverse destination, oh dear one!

Kṛṣṇa gives an extraordinary guarantee: na vidyate vināśaḥ — there is no destruction. Neither iha (here, in this life) nor amutra (in the hereafter). Spiritual effort is never lost.

Kalyāṇa-kṛt — “doer of the auspicious” — one who attempts yoga has planted seeds that inevitably bear fruit. This is the optimistic doctrine of karma-yoga.
