Your very desire for grace is due to grace that already working in you.—-Maharishi Ramana.
Comment; we are not happy what we have. every time we want something different, you may be rich or poor you never satisfy. sometimes we think we will happy when we have a big house but after having it we do not happy. it may be sex, greed, money, fame after having it we do not happy. what is our demand for? our demand is for seeking or finding our real source of life, we can say, God, Nirvana, liberation etc. we can say grace also. it is already working in us. it is like a wave which remains on the ocean and wants to merge in an ocean. without having grace we will never satisfy. that is my views about grace.
my experience of this that when I am doing practice and mind merge in the self it is such an experience of bliss or Samadhi, even you can not explain it but it is our blossoming. you feel new dawn which you can not fell on a king’s throne.
