In Cosmic moral law, all actions will produce reactions, and all causes will produce effects. (Karma). Karma is divided into three main types but the one which is actually in motion, which is responsible for us being the way we are right now, is said to be Destiny or Fate. This is pretty much the Universal Law.
Sri Chinmoy teaches that fate can be nullified or changed by an unchanging will; that the Soul in man is greater than his fate and finally, all can be done if the God-touch is there. Here are two very interesting and profound statements by the God-Man Sri Chinmoy:
"There is a world which is infinitely higher than the planets. From there we can easily create, and we can also delete anything in our fate. We can also add something new as fate can be adjusted by the Grace of the Supreme. If a highly developed seeker gets Grace either from a Spiritual Master or from God, then the planets cannot influence the seeker.
Even in the case of an ordinary seeker, If the Master intervenes, the planets cannot do anything....God's Grace can change anybody's fate. It changes the occult possibilities and transcends the laws of astrology, which are God's cosmic laws." - Grace, P 34-35, (2003), Aum Publications.
One needs to have total faith in one's aspiration and in God's Grace. According to Sri Chinmoy, God is not bound by any plans and changes the plan from time to time. So that "Everything is pre-destined and again everything is not pre-destined, because God Himself is not bound by any law. He is eternally free."
"On the one hand, while creating the Universe, God has made certain laws so that there will be some system, some order. But God has no starting point. He is the starting point, and He Himself is also the Goal. If in His vision he sees something, then the vision will be transformed into reality, but He can also change this vision to arrive at a different reality.
Since God is not bound by anything, we cannot say that everything is pre-destined. It is predestined for one who believes in Fate. But there is a superior force, the force of the infinite Supreme. So God's infinite Grace can easily nullify, expedite and illumine fate and do anything that it wants to do in order to better the consciousness of humanity." - Dipti Nivas, 1976, Agni Press.
This supreme message is repeated in Sri Chinmoy's works and that of Sri Aurobindo. So yes, generally cosmic law works unfailingly, and would coil around us like a snake. Still, Grace is always the last word.
