The progressive growth of the finite consciousness of man towards this Self, towards the universal , the eternal, the infinite, in a word his growth into spiritual consciousness by the development of his ordinary ignorant natural being into an illumined divine nature, this is for Indian thinking the significance of life and the aim of human existance.
God does work through both pure and impure vessels but that does not mean that one should keep nature impure for ever. When the vessel will become pure the urge for action coming from within will be a flawless, definitive action. As long as that does not happen one has to minimize one's activities.
The desire of your vital being is towards work. And the vital being won't find any interest in yoga so long as you do not have any experience of the higher and fuller life that is in yoga. As long as this experience is not there, the vital being will not find any interest.
Thus to act under the guidance coming from above, this is one side of the sadhana, the dynamic side. The other one is the discrimination between the Purusha and the Prakriti. The Purusha will calmly observe, give sanction, choose, but will realise that all this does not belong to him - all these are outside him. This is the static side of the sadhana. These two aspects constitute the basis of Yoga.
Religions, creeds and forms are only a characteristic outward sign of the spiritual impulsion and religion itself is the intensive action by which it tries to find its inward force. Its expansive movement comes in the thought which it throws out on life, the ideals which open up new horizons and which the intellect accepts and life labours to assimilate.
All fanaticism is false, because it is a contradiction of the very nature of God and of Truth. Truth cannot be shut up in a single book, Bible or Veda or Koran, or in a single religion. The Divine Being is eternal and universal and infinite and cannot be the sole property of the Mussulmans or of the Semitic religions only, - those that happened to be in a line from the Bible and to have Jewish or Arabian prophets for their founders.
Spirituality is much wider than any particular religion, and in the larger ideas of it that are now coming on us even the greatest religion becomes no more than a broad sect or branch of the one universal religion, by which we shall understand in the future man's seeking for the eternal, the divine, the greater self, the source of unity and his attempt to arrive at some equation, some increasing approximation of the values of human life with the eternal and the divine values.
Live according to Nature, runs the maxim of the West; but according to what nature, the nature of the body or the nature which exceeds the body? This first we ought to determine.
