This is the human world tree which is also called the kalpa tree. How it is created, how sustenance and destruction take place should all enter your intellects. Just as those are non-living trees, so this is a living tree. The Seed is also living. People sing His praise: He is the Truth and the Living Being. That is, He explains the beginning, the middle and the end of the whole tree to us. No one knows His occupation. You should also know the occupation of Prajapita Brahma.Â
