Sri Jibankrishna Or Diamond said this quote

The term ‘Grace’ has been explained by people just to fulfill the vested interest. But what is its actual meaning? Thakur (Sri Ramkrishna) has said ‘When God within the body wishes to liberate himself, then there will be actual liberation of ‘Atma’ or ‘Soul’. That means spontaneous evolution of life power. This spontaneous evolution which individual gets is called grace. Otherwise the term ‘Grace’ is an abstract idea.
