Śrīmad-Bhāgavatam 7.9.31

Māyāpur, March 9, 1976
Therefore Prahlāda Mahārāja says, idaṁ sad-asad-īśa. Sad-asat, kārya kāraṇa, cause and effect. Just like you have got a cloth. Cloth is made of cotton. So from cotton we prepare thread, and from thread we prepare cloth. So when the cloth is there, the thread has disappeared. When the thread is there, the cotton has disappeared. They are called sad-asat. Sat means which is existing, and asad means which is no longer existing. So this material world is asat. It is simply for the time being an exhibition. So we have to find out the real existence, sanātana existence. That is Kṛṣṇa. We should not be bewildered by seeing this temporary manifestation. Anything material is temporary. It has a date of creation. Everything, whatever you see here in the... Just like this microphone. It has got a date of creation, it will work for some time, and then it will go out of order, and we shall throw it in the street and again it will disappear in the earth, because everything has come out from the earth. This is material world. But we must find out what is the reality. We should not be bewildered by the temporary things. Our Kṛṣṇa consciousness movement is to take the living entity from this temporary world to the spiritual world or to the permanent world, where there is no more annihilation. It is eternal, nitya. Nityaḥ śāśvataḥ.
So we living entities, we are eternal. This is māyā, that I am thinking, "I am this body." This is our ignorance. So the Kṛṣṇa consciousness movement is to deliver the human society from this ignorance, temporary things: "I am this body. This is my country. This is my wife. This is my children. This is... This is mine. This is—ahaṁ mameti [SB 5.5.8]. I am this body, and anything in reference with the body is mine." But actually there is no such thing. This is called māyā. Real thing is, the reality is, Kṛṣṇa, Brahman, Parabrahman. All other things... Therefore Vedic injunction is, "Don't try to remain in this temporary situation." Asato mā sad gamaḥ: "Don't remain this..." But we are so ignorant, our present civilization is so foolish, that they do not know what is sat and what is asat. They want to stay in the asat. They want to make arrangement to stay in this asat, temporary things, forgetting that however nicely you make arrangement in this temporary material world, you'll not be allowed to stay. This is our ignorance. Mūḍha nābhijānāti mām ebhyaḥ param avyayam. Kṛṣṇa says, "These rascals, mūḍha, they do not know what is the permanent stage, sanātana." That is wanted. That is human knowledge. One should know the permanent, not be bewildered by the temporary things. That is ignorance.
