Commentaries and Reflections

Commentary by TKV Desikachar:

“The first six chapters of the Gītā
deal with Karma and Jñāna that
reveal the true nature of oneself.”
– TKV Desikachar on Gītārtha Saṃgraha of Śrī Yāmunācārya Śloka Two

Commentary by Paul Harvey:

“The journey with and through the Bhagavad Gītā
is one of a Vinyāsa Krama with three distinct stages.
Firstly, the Pūrva Aṅga aspect of our journey in the ascension
from confusion to clarity, as epitomised in the first hexad.
Here we start from being disturbingly yoked to Viṣāda
as in the first Chapter, and through a chapter by chapter
process, we deepen our self-inquiry into the nature of who.
In other words, this hexad is an exploration of our relationship
with what we perceive and identify with as if our perennial self.
Through chapters two to five, we learn how to approach and
refine the practice of Dhyāna as in Chapter six, through which
clarity arises in our efforts to cultivate a sense of an inner guide.”
– Paul Harvey on Gītārtha Saṃgraha of Śrī Yāmunācārya Śloka Two
