śrīmadbhagavadgītā pārāyaṇa - pañcadaśo'dhyāyaḥ

The fifteenth chapter of the Bhagavad Gita, known as Purushottama Yoga, is spoken by Lord Krishna to Arjuna. It describes the symbolic Ashvattha tree as a metaphor for the complex structure of the material universe and existence. Through this discourse, Krishna reveals the nature of the Supreme Purushottama, who transcends both the perishable and imperishable aspects of reality. Reciting this chapter is considered immensely spiritually purifying, as it provides seekers with the profound wisdom necessary to detach from worldly illusions, understand the divine hierarchy, and ultimately attain liberation and union with the Supreme Lord.
