IT IS FEELING THAT IS THE LIFE, THE STRENGTH, THE VITALITY, WITHOUT WHICH NO AMOUNT OF INTELLECTUAL ACTIVITY CAN REACH GOD.

Do you not know from the history of the world where the power of the prophets lay? Where was it? In the intellect? Did any of them write a fine book on philosophy, on the most intricate ratiocinations of logic? Not one of them. They only spoke a few words. Feel like Christ and you will be a Christ; feel like Buddha and you will be a Buddha. It is feeling that is the life, the strength, the vitality, without which no amount of intellectual activity can reach God. Intellect is like limbs without the power of locomotion. It is only when feeling enters and gives them motion that they move and work on others
