Till we get the feeling that everything is God and that which is in everybody, is God, we will continue to get rebirth. Grace always exists and when we are peaceful and the mind is subtle then we can feel Grace but Grace is not felt when we are in confusion. It is better to have Godís Grace the size of an atom rather than read millions of books - then our physical eyesight will become spiritual knowledge insight.
We remember all useless things and forget useful things. God took the shape of the lingam for our remembrance. When we see a school, we remember education, when we see a hospital it makes us think of disease and illness and when we see a bank we think about money. In the same way when we see a lingam we remember God.
Siva is immovable God. Sankaracharya is moving God. He met Padmapada for the first time at Manikarnika Ghat (Kasi). Till the end their friendship remained. That is true friendship.
