The main part of the tree is the trunk, then there are the big branches and the twigs that emerge. Gita, the religious scripture, the jewel of all scriptures, is the trunk. After that, all the rest are the creation. Islam, Buddhism, Christianity etc. are all branches of the kalpa tree. In the Gita, it is written: The tree of the human world. So, the significance of the tree is now in your intellects. The main part is the trunk – the original eternal deity religion. This tree is compared to that of banyan tree. That tree is very big. When the tree becomes old, its trunk decays but the branches and twigs remain. It is the same here. Trunk of this tree, which is the deity religion, no longer exists.
