Abstaining from sins and Remembering the name of Allah Ta’ala is the only way to attain peace and tranquility. So learn to make the Zikr of Allah Ta’ala and sit in the company of those Pious People (buzurgs) where the sweetness of the name of Allah is attained. They are those whom Allah Ta’ala, through his love and connection, has granted them an understanding. Go and spend some time with them, take out 40 days and then see for yourself what happens.
If someone is diagnosed with cancer of the lungs and the doctor advises him to go to the mountains of Maree (for treatment by breathing fresh air) would he not go? The Ahlullah have the remedies for spiritual diseases. One attains the love of Allah through the company of the Ahlullah. We can’t see Allah Ta’ala, but our hearts can perceive Him. That is why the special mercies of Allah Ta’ala are always descending upon the hearts of the Ambiya and Auliya.
