In samadi, the mind is not thinking of any object. It is still in the pure subject and has no thought at all. The meaning of 'buddha' means awake tho one who has woken up. Another characteristic: sucamartian ticam yata bud graiamatindriam - acme of bliss of joy. Once you have got it, when you come out of that samadi, you will know one thing for sure,. that which i am, is this, nothing greater than that i have got.
