Human form of life not to work hard like asses, swine and dogs
We are given this human form of life not to work hard like asses, swine and dogs but to attain the highest perfection of life. If we do not care for self-realization, the laws of nature force us to work very hard, even though we may not want to do so. Human beings in this age have been forced to work hard like the asses and bullocks that pull carts.
– Srila Prabhupada, Sri Isopanishad Mantra 3
