The essence of spirituality does not consist in a specialised or narrow interest in some imagined part of life, but in a certain enlightened attitude to all the various situations which obtain in life. It covers and includes the whole of life. All the material things of this world can be made subservient to the divine game, and when they are thus subordained they become auxiliary to the self-affirmation of the spirit.
