Now, Krishna talks about thee glory, uniqueness, mystery, subtility and rareness of Self-knowledge. This is called in Vedanta parlance as Spiritual Knowledge or Paravidya. Aas(h)charyavath pas(h)yathi kas(h)chidaenam aas(h)charyavas vadathi thathaiva chaanya: Aas(h)charyavas(h)chainamanya: s(h)ruNothi s(h)ruthvaapyaena vaeda na chaiva kas(h)chith 2.29 One rare person knows this (Self) as a wonder. In the same way, another one speaks about (this Self) as a wonder. Another one hears of (this Self) as a wonder. Still, another never understands this (Self) inspite of hearing. Atma is always a wonder (Aas(h)charyavath). When you understand atma, it is a wonder and, when you do not understand, it is a wonder to you, how anyone can understand it ! This wonder takes several forms. Atma is something never seen before , something that appears all of a sudden to one who has been taught by a guru, something that is striking. The student understands and looks at the atma as a wonder (Aas(h)charyavath pas(h)yathi). Why? Because he or she now looks at himself or herself as a wonder. When I suddenly discover that I am the whole and everything is centred on me, everything is me, it is definitely a wonder. First, this reality of oneself seems to be an impossibility. Then it becomes a vague possibility. Finally, it is real, true ! We experience this atma all the time. Only because of the atma, do we experience the world. This atma is very evident as ananda in moments of joy when we discover ourselves to be full (purna). But, still, when it is pointed out that we are that whole, we do not understand – which is another wonder (s(h)ruthvaapyaena vaeda na chaiva kas(h)chith This verse explains why atma is so difficult to understand. This verse may also be interpreted in this manner. He that sees, hears and speaks of the Self is a wonderful man. Such a man is very rare. He is one among many thousands. Thus the Self is very hard to understand. Love, Chithra.
