Bhagavad Gita -Swami Sivananda
Chapter-15 : THE YOGA OF THE SUPREME SPIRIT
Summary of Fifteenth Discourse
This discourse is entitled “Purushottama Yoga” or the “Yoga of the Supreme Person”. Here Lord Krishna tells us about the ultimate source of this visible phenomenal universe from which all things have come into being, just like a great tree with all its roots, trunk, branches, twigs, leaves, flowers and fruits which spring forth from the earth, which itself supports the tree and in which it is rooted.
Sri Krishna declares that the Supreme Being is the source of all existence, and refers allegorically to this universe as being like an inverted tree whose roots are in Para Brahman, and whose spreading branches and foliage constitute all the things and factors that go to make up this
creation of variegated phenomena. This is a very mysterious “Tree” which is very difficult to understand, being a product of His inscrutable power of Maya; and hence a marvellous, apparent appearance without having actual reality. One who fully understands the nature of this Samsara-Tree goes beyond Maya. To be attached to it is to be caught in it. The surest way of transcending this Samsara or worldly life is by wielding the excellent weapon of dispassion and non-attachment.
