Acharya Prashant explains that while the ultimate truth or the soul is one, the expressions of various gurus differ because they are individuals shaped by their specific time, language, and circumstances. A speaker's personality acts as the medium for expression; for instance, Saint Kabir spoke in the language he knew, not in Sanskrit or foreign tongues. Furthermore, the nature of the teaching depends heavily on the listener. Shri Krishna spoke differently to Arjun before and after the war, and his tone varied when addressing the Gopis. The effort required to explain concepts also changes based on the recipient's readiness, as seen in the contrast between the Bhagavad Gita and the Ashtavakra Gita.
