To “immerse” oneself “in the sea of sacrifice, with his heart fixed upon the beauty of the All-Glorious”

Regarding the statement in "The Hidden Words", that man must renounce his own self, the meaning is that he must renounce his inordinate desires, his selfish purposes and the promptings of his human self, and seek out the holy breathings of the spirit, and follow the yearnings of his higher self, and immerse himself in the sea of sacrifice, with his heart fixed upon the beauty of the All-Glorious.
