काङ्क्षन्तः कर्मणां सिद्धिं यजन्त इह देवताः।
क्षिप्रं हि मानुषे लोके सिद्धिर्भवति कर्मजा।।4.12।।
।।4.12।। (सामान्य मनुष्य) यहाँ (इस लोक में) कर्मों के फल को चाहते हुये देवताओं को पूजते हैं क्योंकि मनुष्य लोक में कर्मों के फल शीघ्र ही प्राप्त होते हैं।।
For the most part persons who desire the material fruits of their actions never worship the Supreme Lord Krishna who is the super soul existing within all living beings and who is the ultimate recipient of all worship and offerings as confirmed in the previous verse. It is very rarely seen that the materialists are inclined to His worship. Instead they worship the demi-gods and other lesser entities. Why is this so? It is because by worshipping them the seekers of material possessions such as wealth, power and dominion find quick results in the fulfilment of their material desires. Manuse loke means in the mortal worlds. This includes all material worlds everywhere in creation. Such persons in these worlds oblivious to the true purpose of human existence due to a vast accumulation of sinful reactions that have not been exhausted from time immemorial. Desire immediate results for their actions causing them to get more and more reactions. Such people worship that which gives temporary material rewards and foolishly pursue transient material objectives even foolishly attempting to gain immortality in their corporeal physical body. Only such a rare being who fearful of samsara or transmigration from physical body to physical body in the endless cycle of birth and death, who aspires for moksa or liberation from the cycle of birth and death, only this rare being would engage themselves in karma yoga or the performance of prescribed Vedic activities as propitiation to the Supreme Lord Krishna. The next verse reveals how to release oneself from sin which obscures ones perception from realising the need to engage in karma yoga.
