The material is also Kṛṣṇa. Kṛṣṇa is everything. God is everything. Bhūmir āpo 'nalo vāyuḥ khaṁ mano buddhir eva ca (BG 7.4). What is this material world? Kṛṣṇa says, "This bhūmi, this land, āpaḥ, the water, the ocean, that is My energy." There is no difference between the energy and the energetic. Just like the sunshine is the energy of the sun. The sunshine is also heat and light, and the sun is also heat and light. Similarly, this bhūmir āpo 'nalo vāyuḥ khaṁ mano buddhir eva ca, these material things are the energy of Kṛṣṇa; therefore these energies are also Kṛṣṇa. So if we study about bhakti-mārga, about Bhagavad-gītā, Śrīmad-Bhāgavatam, then we shall gradually understand. Therefore Prahlāda Mahārāja says that "Begin to understand bhāgavata-dharma, what is God, what He is like, what is His relationship with Me."
Why you should understand God from the beginning of life? That is explained here: because the human life is meant for understanding God. The cats and dogs, they cannot understand God, but although he has got this material body like us, the cats' and dogs' body and my body, if we make analysis, there is some blood, there is some muscle, there is some bone, there is some urine and stool. You'll find in the dog's body and in my body. Although these material things I am not; I am different from this muscle or blood or air, whatever it is composition. I am different. That also we can analyze what is this body. This body, first of all, you analyze that when there is no breathing, the life is lost. Do you think that breathing is life? No. Analyze it. What is breathing? It is a air only, little air. Do you mean to say when this breathing is stopped you can inject some air by some machine and life will come? No, that will not come. Therefore air is not life. Neither the blood is life, neither the bone is life, neither the muscle is life. Life is different from all these things. That you have to learn. That is called bhāgavata-dharma.
So, in this way . . . This Kṛṣṇa consciousness movement, don't think that it is a sectarian religious system. No. It is a science, bhāgavata-dharma, the science of Kṛṣṇa. Try to understand the science of Kṛṣṇa. We have got so many books to educate people about this science. Not that simply we are talking sentimentally. It is . . . Everything is scientific reason, philosophy. But the simple method is so easy to perform that anyone can understand very easily. What is that? Sarva-dharmān parityajya . . . (BG 18.66). What Kṛṣṇa says, you accept. Then you will understand what is bhāgavata-dharma, what is God, what you are, what is this world, what is the relationship, why you should become a devotee of God. Everything is explained in the Bhagavad-gītā As It Is. Try to understand this bhāgavata-dharma and be happy in your life.
