The information we get from Bhagavad-gītā, that God is sitting within your heart. That is a fact. Not only within your heart, my heart, the animal's heart—everyone, sarva-bhūtānāṁ. Sarva-bhūtānāṁ means "Of all living entities." It is not that simply God is sitting within human body's heart, but He is sitting in everybody's heart.
- īśvaraḥ sarva-bhūtānāṁ
- hṛd-deśe 'rjuna tiṣṭhati
- bhrāmayan . . .
- (BG 18.61)
And He is causing the transmigration of the soul, yantrārūḍhāni, sitting on the machine of this body. So both the living entity and God is sitting within this machine.
(aside) You cannot sit cross-legged.
So within your body, within my body, and everyone's body—even an ant's body, elephant's body, tree's body, fish's body, all bodies. There are different types of body. Don't think that the lower animals—birds, bees, trees, plants, insects—they are different from us. No. They are also the same living entity, but in different dress.
Just like we are sitting, so many boys and girls, you are in different dress. But essentially your dress may be different, but you are all human beings. Similarly, there are 8,400,000 different forms of living entities. They are outward dress, the body, which is made of this five elements—earth, water, air, fire, gross five elements—and three subtle elements—mind, intelligence and ego. They are all living entities. They are not in quality as living entities; they are the same, but they are differently dressed. Therefore the learned, who know that every one of us who is a living spark, spiritual spark, we are encaged within this body.
