Gita 15.1

Oordhvmoolam’, adhHshaakham’, ashvttham’, praahuH, avyyam’,
Chhandaasi, yasya, parnaani, yaH, tam’, ved, saH, vedvit’ ||1||

Translation: (Oordhvmoolam’) with the roots above in the form of Purna Parmatma Aadi Purush Parmeshwar (adhHshaakham’) the branches below in the form of the three gunas i.e. Rajgun-Brahma, Satgun-Vishnu and Tamgun-Shiv (avyyam’) imperishable (ashvttham’) is extensive Pipal tree (yasya) whose (chhandaasi) just as there are verses in Vedas similarly the world-like tree also has divisions, small-small parts or twigs and (parnaani) leaves (praahuH) are said to be (tam’) that tree of world (yaH) who (ved) knows in detail (saH) he (vedvit’) is completely knowledgeable i.e. is Tatvdarshi. (1)

Translation: With the roots above in the form of Purna Parmatma Aadi Purush Parmeshwar and the branches below in the form of the three gunas i.e. Rajgun-Brahma, Satgun-Vishnu and Tamgun-Shiv, it is an imperishable, extensive Pipal tree, whose divisions, small-small parts, just as there are verses in Vedas, are said to be twigs and leaves. One, who knows that tree of world in detail, is completely knowledgeable i.e. is Tatvdarshi.

Meaning: In Bhagavad Gita Chapter 4 Verse 34, it is stated that Arjun, go to the Tatvdarshi saints, who know the Tatvgyan of Purna Parmatma and obtain the path of bhakti of Purna Parmatma with humility; I do not know the path for attaining that Purna Parmatma. In this very Bhagavad Gita Chapter 15 Verse 3 also, has mentioned that I will not be able to tell the extent of this world-like tree i.e. creation in this discussion here i.e. in this knowledge of Gita because I do not know about its beginning and end (to the extent it is spread i.e. description of all the brahmands). Regarding a Tatvdarshi saint has explained in this Bhagavad Gita Chapter 15 Verse 1 that how would that Tatvdarshi saint be, who will give a complete description of the tree of world that the base is Purna Parmatma, trunk is Akshar Purush i.e ParBrahm, a big branch is Brahm i.e. Kshar Purush and smaller branches are the three gunas (Rajgun-Brahma Ji, Satgun-Vishnu Ji and Tamgun-Shiv Ji) and the leaves are this world i.e. he will give a detailed description of all the brahmands; he is a Tatvdarshi saint.
