Everything I have personally experienced, and that also has been expressed by the leaders of the great religions points to the fact that a global spirituality already exists and was intrinsically there from the start as God (by whatever name) is one and is indivisible - everywhere outside time and place.
The Bhagavad-Gita calls on humanity to dedicate body, mind and soul to pure duty and not to become mental voluptuaries at the mercy of random desires and undisciplined impulses.
It is not given to man to know the whole Truth. His duty lies in living up to the truth as he sees it, and in doing so, to resort to the purest means, i.e., to non-violence. God alone knows absolute truth. Therefore, I have often said, Truth is God. It follows that man, a finite being, cannot know absolute truth. Nobody in this world possesses absolute truth. This is God's attribute alone. Relative truth is all we know. Therefore, we can only follow the truth as we see it. Such pursuit of truth cannot lead anyone astray.
I know, to banish anger altogether from one's breast is a difficult task. It cannot be achieved through pure personal effort. It can be done only by God's grace.
I do feel that spiritual progress does demand at some stage that we should cease to kill our fellow creatures for the satisfaction of our bodily wants.
