Page 15 of 25Atman does not need any purification because it is ever pure, ever free, ever wise. We are not fully aware of that purity because we're so aware of the things covering the Self, such as our negative samskaras, karmas, vasanas. We need to cultivate ourselves every single moment of our life.
Human beings can't live without performing actions and that leads to being bound by karma. Some day we see we are bound so tight that it is very hard to undo. Reading from the Bhagavad Gita every day helps to keep us on track.
You change as you make some progress. The same sentence or book will have a different meaning. You do not react when someone says something as you did last year. You always will wish the best to the person who has harmed you. This is the quality of a meditator, of a saint. Satsanga means company of the saintly, the saintly qualities we are cultivating within. They are there; we need to become aware of them. We need to purify the samskaras that are holding us back from being aware of our true nature.
In the first chapter of the Gita, Arjuna is confused, he doesn't know what to do. We don't even believe we have the capacity to do something because there is a big curtain in front of the buddhi. If you cultivate your buddhi, any decision or advice is correct. Buddhi is the source of intuition, that flows from the Atman, from the individual soul. It comes through the buddhi to you. If the buddhi is dusty, then you cannot recognize there is a message or advice for you. Buddhi is faithful to us and will guide us in any incident or situation in life. Arjuna is well capable, he has elevated himself, but does not know how to have access. Krishna gives him confirmation he is capable.
Lord Krishna addresses Arjuna with different names representing qualities within Arjuna. He is trying to tell him not to be confused, to use his will power and self respect and confidence. Arjuna is that aspect in us who is hungry for knowledge. He has a burning desire for elevation but still is confused. If you have that, it means you are Arjuna. And you have Krishna with you, who wants to guide you. Krishna is your buddhi, your Atman. He guides you, leads your chariot in the right way. It depends on how clear the buddhi is. Your chariot will go in that direction.
Arjuna is shaking because he doesn't want to fight his elders and respected teachers. That happens in our life. Sometimes we don't have a choice. You have to rise above your circumstances.
