Please, tell me a  litany (dua), which creates overwhelming love of Allah and His messenger, ever present fear of Allah in my heart, nonexistence or a decrease in the love of the worldly and complete fearlessness from other-than Allah.

Hakim al-Umma Mawlana Ashraf Ali Thanawi (Allah have mercy on him)  replied,

صوفی نہ شود صافی تا در نہ کشد جامی

بسیار سفر بایدتا پختہ شود خامی

(A sufi does not attain purity until after a toil and struggle.

A lengthy journey is required to attain perfection.)

Being firm on the zikr (remembrance), shugal (mental exercise of specific forms of remembrance), reading useful books (i.e. of Tasawwuf) and keeping company of pious (ahlulAllah) for a considerable duration of time leads to attainment of these treasures.

There is no specific dua for it.
