In psychological fact this method translates itself into the progressive surrender of the ego with its whole field and all its apparatus to the Beyond-ego with its vast and incalculable but always inevitable workings. Certainly, this is no short cut or easy sadhana. It requires a colossal faith, an absolute courage and above all an unflinching patience. For it implies three stages of which only the last can be wholly blissful or rapid,—the attempt of the ego to enter into contact with the Divine, the wide, full and therefore laborious preparation of the whole lower Nature by the divine working to receive and become the higher Nature, and the eventual transformation. In fact, however, the divine Strength, often unobserved and behind the veil, substitutes itself for our weakness and supports us through all our failings of faith, courage and patience. It “makes the blind to see and the lame to stride over the hills.” The intellect becomes aware of a Law that beneficently insists and a succour that upholds; the heart speaks of a Master of all things and Friend of man or a universal Mother who upholds through all stumblings. Therefore this path is at once the most difficult imaginable and yet, in comparison with the magnitude of its effort and object, the most easy and sure of all.
