Based on Bhagavad Gita Chapter 02, Text 59
By Chaitanya Charan Das
A bird may be physically restrained by a cage, but it can’t be mentally restrained from dreaming and craving about the grains it could have been feasting on in the field.
The bird can’t be blamed for its sensual preoccupation because subhuman beings such as birds don’t have the developed consciousness to seek any purpose of existence higher than pandering to the bodily demands of eating, sleeping, mating and defending. We humans do have that evolved consciousness, but we need to exercise it for perceiving and pursuing a higher purpose. Otherwise, our higher potential remains unutilized and we remain restricted to the same stereotyped activities that drive lower beings.
