You are human being. You are sitting here. If you like, you can move immediately. But the tree cannot move. "Stand up there." By whose order? By whose order? By God's order. "You must stand up." Don't take it, I mean to say, neglectfully. It is very serious. According to Vedic calculation, this tree which is grown here, that living entity was sometimes owner or occupier of this house, and it had so much attachment that it cannot go out of this house. Therefore he has been given this body, tree: "All right, you live here and stand up."
Sometimes we become ghost. If we become too much attached, we cannot leave. Therefore too much opulent apartment, opulent life, is not very good for spiritual advancement because we get too much attached to it. My Guru Mahārāja used to advise us that, "It is better to live in rented house than to possess own house." Why? Because if we possess our own house, we'll be more attached.
Because the life's program is jñāna-vairāgya, knowledge and renouncement. One should have sufficient knowledge to understand his constitutional position as a living entity. And he must develop renouncement, vairāgya. Because attachment sometimes leads me to become a tree, to become a mouse, to become a serpent in the same house. Attachment. After all, you may decorate your house. You may purchase a nice house; you decorate it very nicely. But you have to leave it. You cannot live here permanently. That is not possible. Either make your country very nice, very nice city, very decorated city, or your house, apartment, wife, children, very nice decorated, but you'll not be allowed to remain.
