Dashing Scorpio's answer is excellent!To continue, Aspirations manifest themselves. So for example, you receive through Grace in prayer, and then you share it with the spiritually hungry world. Men and women of God are constantly manifesting in this world. We share, in a small way, like a smile, or in a big way through a spiritual concert for thousands!
I take part from time to time, and indeed organise something called The World Harmony Run or Sri Chinmoy's Oneness-Home Peace Run. It is quite successful and inspires millions around the globe.
Aspiration is the beginning and the end of the journey. Again, it is a birthless and deathless sojourn. It comes from a selfless inner cry and that cry is sooner or later manifested in the world in which we live. The intensity of inner aspiration demands expression. I have written a great deal about both in my book: My Guru, Sri Chinmoy: Life And Teachings. Both inspiration and aspiration go together. Peace.
