The Tiny World of Modern Science
During a morning walk in April of 1973, at Venice Beach, Los Angeles, Śrīla Prabhupāda discusses modern science and its high priests: “They claim to have millions of dollars worth of knowledge, but if you ask them a question, they simply give you a postdated check. Why should we accept it? They cannot even produce a spear of grass through their biological or chemical experiments. Nonetheless, they are claiming that the creation is produced by some chemical or biological method. Why does no one question all this nonsense?”
Śrīla Prabhupāda:  The whole world of science and technology is running on the false idea that life is born from matter. We cannot allow this nonsensical theory to go unchallenged. Life does not come from matter. Matter is generated from life. This is not theory; it is fact. Science is based on an incorrect theory; therefore all its calculations and conclusions are wrong, and people are suffering because of this. When all these mistaken modern scientific theories are corrected, people will become happy. So we must challenge the scientists and defeat them. Otherwise they will mislead the entire society.
Matter changes in six phases: birth, growth, maintenance, production of by-products, dwindling, and death. But the life within matter, the spirit soul, is eternal; it goes through no such changes. Life  appears  to be developing and decaying, but actually it is simply passing through each of these six phases until the material body can no longer be maintained. Then the old body dies, and the soul enters a new body. When our clothing is old and worn, we change it. Similarly, one day our bodies become old and useless, and we pass on to a new body.
As Kṛṣṇa says in the  Bhagavad-gītā  [2.13],  dehino 'smin yathā dehe kaumāraṁ yauvanaṁ jarāl tathā dehāntara-prāptiḥ : “As the embodied soul continually passes, in this body, from boyhood to youth to old age, the soul similarly passes into another body at death.” And a little later [2.18]:  antavanta ime dehā nityasyoktāḥ śarīriṇaḥ . This means that only the material body of the indestructible and eternal entity is subject to destruction. This material body is perishable, but the life within the body is  nitya , eternal.
