na tu sannyasinam kvacit

Translation by His Divine Grace A. C. Bhaktivedanta Swami Srila Prabhupada:
For one who is not renounced, the threefold fruits of action – desirable, undesirable and mixed – accrue after death. But those who are in the renounced order of life have no such result to suffer or enjoy.

Purport by His Divine Grace A. C. Bhaktivedanta Swami Srila Prabhupada:
A person in Krishna consciousness acting in knowledge of his relationship with Krishna is always liberated. Therefore he does not have to enjoy or suffer the results of his acts after death.
