Why you have got different types of bodies? We have manufactured it. God has given us facility. I wanted to become such and such. He has given us facilities, "All right, you become such and such." If I want to become a tiger, God will give me all the facilities to become a tiger. He will give me facilities, paws and nails and teeth, so that immediately I can capture any animal, and with the instruments which He has provided within my body, I can immediately scratch it into pieces and eat.
Similarly, you will find . . . you see the cranes. They have got big beaks. Why? Because they have to catch fish from within the water, so the beak must be very long. So there is facility. The hog has different mouth, because he has to eat stool. So a different kind of body.
So these bodies means we have manufactured according to our different mentality. Kṛṣṇa says that, "You stop all this business. Simply you are migrating, or transmigrating, from one body to another or one planet to another. That will not make you happy." Sarva-dharmān: "You just surrender unto Me. Because you are meant . . . your original creation is meant for serving Me." Just like this body.
