Text 12 

anistam istam misram ca
tri-vidham karmanah phalam
bhavaty atyaginam pretya
na tu sannyasinam kvacit

Translation

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.

Commentary by 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.

Commentary by Sri Visvanatha Cakravarti Thakur

The fault of not following this process of tyaga is described. Those who do not renounce in the prescribed way get results in the form of suffering of hell (anistam), the pleasures of svarga (istam) and human birth (misram) in the next life (pretya).
