All religions have some truth in them, but none has the whole truth; all are created in time and finally decline and perish. Mahomed himself never pretended that the Koran was the last message of God and there would be no other. God and Truth outlast these religions and manifest themselves anew in whatever way or form the Divine Wisdom chooses.
There is a veil between the Supermind above and the lower Prakriti below - the veil of ingrained formations. This veil may completely withdraw or be partially withdrawn. Thus even if there is some little opening, with the contact of Light from above the lower nature will get slowly changed.
The human mind moves always forward, alters its viewpoint and enlarges its thought substance, and the effect of these changes is to render past systems of thinking obsolete or, when they are preserved, to extend, to modify and subtly or visibly to alter their value.
What is required is faith. Man has body, life and mind but that is not all that constitutes man. He has risen to the mind as a result of evolution. Now a higher consciousness will be evolved - this I call Supermind. It is the instrument of the Divine Consciousness, the Truth-Consciousness.
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.
The seers of ancient India had, in their experiments and efforts at spiritual training and the conquest of the body, perfected a discovery which in its importance to the future of human knowledge dwarfs the divinations of Newton and Galileo , even the discovery of the inductive and experimental method in Science was not more momentous.
Your mind has some clearness and capacity for right thinking; it opens towards the heights, but for its own sake, - to receive light from above for its own activity.
