According to the provided texts, what is considered the primary characteristic of devotion, and how do different sages offer alternative perspectives?

The texts present a multifaceted view of devotion. The main characteristic, as stated by scholars of Vedas and enlightened teachers in Chapter 1, is 'seeking one’s own true nature'. However, the passages also introduce other valid paths. Parashara and Vyasa define devotion as the expression of love through worship and rituals, a path known as 'Archan'. Garga Acharya, as mentioned in Chapter 1, describes devotion as the mind becoming absorbed in singing the Lord’s praises until it merges with the divine. Finally, Shandilya’s perspective is that devotion involves constant self-remembrance, listening to discourses, and performing prescribed duties for one's own welfare.
