Hell is where you are and Paradise where you are not. - Abū-Sa'īd Abul-Khayr

If you wish that God should dwell in your heart, purify your heart from all save Him for the king will not enter a house filled with stores and furniture. He will only enter a heart which is empty of all save Himself.

Freedom from lower qualities is an essential qualification required for spiritual progress.

Through love we're slain, the world's our slaughter house
We've no food nor sleep, the world's our cookhouse.
We've no desire for paradise, because
Our hell's a hundred times loftier than that.
