On The Principle of Founder-Ācārya
When you are working within the Kali-yuga, you are working within the Ācārya system, where there is a Founder-Ācārya. So that person is the Paramahaṁsa because they know perfectly what to do in this age. And knowing what to do then everybody else follows them. Relevant instruction means, the Ācārya said this, so we give relevant instruction how to understand what the Ācārya said.
