In Chapter 15 – Puruṣottama Yoga (The Yoga of the Supreme Person) of Swami B.G. Narasingha’s Bhagavad-gītā, Kṛṣṇa compares the material cosmos to a great banyan tree with it's roots above and branches below - a reflection of reality. He says one must cut this tree down with the weapon of detachment and search out knowledge of the supreme abode of Kṛṣṇa.
