tat-sanga
by association with the prostitute of intelligence
bhramsita
taken away

exactly like a person who has a polluted wife

iha
in this world
kim asat-karmabhih bhavet
what can be the benefit of performing temporary fruitive activities

(Narada Muni had also spoken of a man who is the husband of the prostitute. The Haryasvas understood this as follows.) If one becomes the husband of a prostitute, he loses all independence. Similarly, if a living entity has polluted intelligence, he prolongs his materialistic life. Frustrated by material nature, he must follow the movements of the intelligence, which brings various conditions of happiness and distress. If one performs fruitive activities under such conditions, what will be the benefit?
