Having Faith in the Divine Grace

I ask you to have faith in the Divine, in the Divine Grace, in the truth of the sadhana, in the eventual triumph of the spirit over its mental and vital and physical difficulties, in the Path and the Guru, in the existence of things other than are written in the philosophy of Haeckel or Huxley or Bertrand Russell, because if these things are not true, there is no meaning in the Yoga.
