The Grace of God can break the shackles of karma and illusion. There are four types of grace that bless each human being.
The Grace of God:
He has given us a human body. Without the grace of the Almighty, we would have never got a human birth. Many learned scholars think that human birth results from good deeds like charity or pilgrimage, but this is incorrect. We know that life revolves in 8.4 million species, so someone would have come from being an elephant, others from pigs, and still others from dogs or donkeys. Which pious actions would all these other species have done by which they were rewarded with a human birth? It is only by the unbounded grace of the Almighty that one gets a human body.
The Grace of Scriptures:
Without scriptures, our condition would have been like a blind animal. The scriptures guide us by telling us that God is within and Brahmgyan (Self-knowledge) is a must, and only the Guru (Spiritual Master) can provide us with this knowledge. The scriptures say that no one can get the knowledge of truth without a Spiritual Master; there is no devotion without knowledge and no salvation without faith. The Master is there to take us across the worldly ocean. A challenging job becomes easy after surrendering to the Master.
The Grace of Guru:
It is the grace of the Guru (Spiritual Master) when he provides us with the technique to remember God and eventually help us find Him inside us. Guru will only tell us the path to salvation but would not automatically give us salvation. This grace is a fruit that is attained only after our hard work and faithful, sincere efforts. It comes on its own when a seeker has made maximum effort. When all efforts have been made and all efforts have been exhausted.
The Grace of one-self:
It is the grace that one has to do on the self. It has the will to undertake a purposeful life journey, do life's spiritual work, and prepare oneself.
