Just like we are sitting in this loft. So by association of this Bowery Street, always dust is coming in this room, and it is being stuck up, layer after layer, similarly, by association of this material contamination, we have in our heart accumulated so many material dust. The whole thing, our progress of spiritual life, our progress of spiritual realization, is checked only because we have got some misunderstanding of our identification. The identification is that "I am this body." That's all. Yasyātma-buddhiḥ kuṇape tri-dhātuke (SB 10.84.13).
This is also described in Śrīmad-Bhāgavatam, that "One who is identified with this body of three elements..." This body is made of... According to Ayurvedic medicine system, this body is made of tri-dhātu: tejo-vāri-mṛd. That is also stated in the Bhāgavata, tejo-vāri-mṛd. That means heat, water and earth. Heat, water and earth. The whole material creation is a combination of these three things, tejo-vāri-mṛd. Tejaḥ means heat, or fire, and vāri means water, and mṛd means earth. So this body is earth, matter. These grains, the grains which we eat, that is also earth transformation. And now, by eating grains, this place is transformed. This is also earth. So we are seeing a very nice, beautiful, but it is earth. So it is made by interaction of this heat and water. That is the process going on, nature's creation. So yasyātma-buddhiḥ kuṇape tri-dhātuke (SB 10.84.13).
