When you develop devotion and turn all your love towards God, everything that is necessary will be added unto you. You will develop the capacity to sacrifice yourself. You will expand in love. Love is the very life breath of a human being. Without love you cannot live.
Love is a very sacred quality.
Love is not for the sake of others but only for the higher self. But all too frequently, through delusion, this sacred love for the atma , the one self, is diverted towards the body. Everywhere in the world we find this disease of identification with the body.
