Hakim al-Umma Mawlana Ashraf Ali Thanawi (Allah have mercy on him) wrote in reply to a salik’s letter who had complained of decreasing interest and engrossment,

‘There are various ways of worshipping. Contemplation is also worship, remembrance without counting is also worship, and considering one’s self to be unprivileged, undeserving, deficient and imperfect is also worship. Hence, the objective is always achievable.

However, there are two undesired states, disobedience (ma’asiyet) and heedlessness (gaflah). And all praise is to Allah, you do not have them.

The overwhelming rapture (ghalba) and engrossing interest (shauq) are from the transitional states. The lack of them is not detrimental for the salik. Moreover, these states can not stay at the same level for ever.’
