Prabhupada 0085 - Culture Of Knowledge Means Spiritual Knowledge
Lecture on Sri Isopanisad, Mantra 9-10 -- Los Angeles, May 14, 1970
"The wise have explained to us that one result is derived from the culture of knowledge, and it is said that a different result is obtained from the culture of nescience."
So yesterday we have explained to some extent what is the culture of nescience and what is the culture of knowledge. Culture of knowledge means spiritual knowledge. That is real knowledge. And advancement of knowledge for comforts or to protect this material body, that is the culture of nescience. Because however you may try to protect this body, its natural course will take place. What is that? Janma-mṛtyu-jarā-vyādhi (BG 13.9). You cannot relieve this body from repeated birth and death, and while manifested, disease and old age. So people are very much busy for culturing knowledge of this body, although they are seeing every moment that this body is decaying. The death of the body was registered when it was born. That's a fact. So you cannot stop the natural course of this body. You must meet the process of the body, namely, birth, death, old age, and disease.
So Bhāgavata says, therefore, yasyātma-buddhiḥ kuṇape tri-dhātuke (SB 10.84.13). This body is made of three primary elements: mucus, bile, and air. That is the Vedic version and Āyurvedic treatment. This body is a bag of mucus, bile, and air. In old age the air circulation becomes disturbed; therefore old man becomes rheumatic, so many bodily ailments. So Bhāgavata says, "One who has accepted this combination of bile, mucus, and air as self, he is an ass." Yes. Actually, this is the fact. If we accept this combination of bile, mucus, and air as myself... So intelligent person, a very great philosopher, very great scientist, does it mean that he's a combination of bile, mucus and air? No. This is the mistake. He's different from this bile or mucus or air. He's soul. And according to his karma, he's exhibiting, manifesting his talent. So they do not understand this karma, the law of karma. Why we find so many different personalities?
