Chapter Two

1. If you think, ‘I know it well’, you know just a little the form of brahman that part of it which is you and that part of it which is among the gods. I think you should investigate that unknown:

2. I do not think, ‘I know it well,
And I do not know, ‘I don’t know it.’
Whoever of s knows it, knows it,
And does not know, ‘I don’t know it.

3. Is thought of by the one to whom it is unthought;
The one by whom it is thought of he does not know
It is not understood by the understanders;
It is understood by those who do not understand.

4. It is thought of when it is realized by awakening to it:
So one finds immortality.
Though oneself (atman) one finds power:
Though wisdom one finds immortality.

5. If, here, one has known it, it is truth;
If, here, one has not know it great destruction!
The wise discern it in every being,
And when they leave this world become immortal.
