Srutayah, scriptures. Suppose somebody sticks to the scriptures. So scriptures, there are different types of scripture. So they are vibhinna. Vibhinna means different types. So how we can become purified by, even by following the scriptures? Tarko 'pratisthah smrtayo vibhinna na casav rsir yasya matam na bhinnam. Muni means thoughtful, philosophers. If we follow a particular type of philosopher, that is also not perfect because I may be under the care of a philosopher, frog philosopher. So that is also not sure. Tarko 'pratisthah smrtayo vibhinna na casav rsir yasya matam na bhinnam, dharmasya tattvam nihitam guhayam.

Therefore to become pure or to understand the essence of purity is very confidential. It is not to be acquired by our own efforts, by argument or by being expert in scripture or by becoming a philosopher or a similar way. It is very confidential. Then how? Mahajano yena gatah sa panthah [Cc. Madhya 17.186]. You have to follow a pure devotee, acknowledged devotee. Similarly, in the Bhagavad-gita, if we follow Arjuna, then we understand Bhagavad-gita as it is. But if we don't follow Arjuna, if we follow somebody, Dr. Frog, or create our own interpretation, then we remain impure. So mahajano yena gatah sa panthah. We have to follow the footprints of mahajana, great soul.
