Continue spiritual practices till the spiritual practices themselves abandon you. - Abu al-Hassan al-Kharaqani

There are some devotees of the Lord who are His beloveds. When they call Him by name, all the birds of air and beasts of the forest stand in silence whilst the angels in heaven shudder and the earth and the heaven and illuminated. Such is the majesty of the utterance of the Name by them that the earth stans quaking.

Whosoever by God's grace sees Him sees not creatures. He who attains to the vision of the Lord is lost to himself.

The greatest activity is the remembrance and recollection of the Lord and after that come, in order of preference, purity of life, charity and austerity.
