Q. What is the significance of one’s free will and efforts?
A. As Krishna has unlimited freewill, so we have minute freewill, by which we can choose and desire to enjoy in so many ways in this world, and make efforts to attain them. Alternately, by our freewill we can choose to act in relationship with Krishna and offer our efforts in His service. By doing our prescribed duties without attachment to the results, as advised by Krishna, we are still exercising our freewill, but in subordination to or in harmony with the Supreme Will.
Srila Prabhupada often gave the simple example of the finger in relation to the body. If a finger decides to feed itself instead of doing its prescribed function of bringing the food to the mouth, and detaches itself from the body, then despite working hard, its efforts will bring no benefit to the finger. Similar will be our efforts for obtaining our individual interests in this world apart from Krishna. Such efforts may bring some temporary enjoyment but ultimately leaves the soul suffering the miseries of material existence.
