Srimad Bhagvadam 4.21.23
The perfection of one’s execution of his appointed duties is the ultimate satisfaction of the Supreme Lord. The word kāma-sandohāḥ means “achievement of the desired result.” Everyone desires to achieve the ultimate goal of life, but in modern civilization the great scientists think that man’s life has no plan. This gross ignorance is very dangerous and makes civilization very risky. People do not know the laws of nature, which are the rulings of the Supreme Personality of Godhead. Because they are atheists of the first order, they have no faith in the existence of God and His rulings and therefore do not know how nature is working. This gross ignorance of the mass of people, including even the so-called scientists and philosophers, makes life a risky situation in which human beings do not know whether they are making progress in life. According to Śrīmad-Bhāgavatam (7.5.30), they are simply progressing to the darkest region of material existence (adānta-gobhir viśatāṁ tamisram). The Kṛṣṇa consciousness movement has therefore been started to give philosophers, scientists, and people in general the proper knowledge about the destiny of life. Everyone should take advantage of this movement and learn the real goal of life.
