Chazon Ish in "Emunah Ubitochon" describes the emotions that awareness of Hashem brings:
"When a person merits becoming aware of the reality of the Almighty's existence, he will experience limitless joy. His soul is enveloped in sanctity, and it is as though the soul has left the body and floats in the upper Heavens. When a person transcends to this level, an entirely new world is open to him. It is possible for a person to be momentarily like a celestial being, [while at the same time] in this world. All of the pleasures of this world are as nothing compared to the intense pleasure of a person cleaving to his Creator."
