Hazrat Hakeemul Ummat Mawlana Ashraf Ali Thanawi ra said;
“In conclusion what is known as fana (annihilation) is an extremely lofty from of love.
That is, all other-than Allah SWT realtionships are so much suppressed that nothing remains to share being worthy of worship. This is the end result of لا اله الاالله .
Neither there exists any thing worthy of being an objective or goal. That is;فليعمل عملا صالحا ولا يشرك بعباده ربه امدا
Nor there exists in the eyes of the salik (seeker) any one besides Him. That is; كل شئى هالك الا وجه”
