A spiritual aspirant wrote,
In the previous condition the attention towards Allah was increased and desire to commit sinful was very subdued. Moreover, a sort of spiritual serenity, calmness and attentiveness was present. However, the condition is not like this anymore. The desire to commit sinful activities becomes very strong sometimes. And the previous serenity is no more.
In this condition I feel miserable, please, pray for me to be steadfast on the right path.
Hakim al Umma Maulana Ashraf Ali Thanvi (Allah have mercy on him) replied,
‘This is the time of subsequent struggle (against desires of nafs) (mujahida e thania) after the completion of the initial struggle (at the onset of this path). The accomplished seeker (wasil) who in unaware of this suspects returning (to previous heedless state) (rij’at). Sometimes he is so dejected that he gives up (the good deeds and abandons the struggle to resist sinful). In reality, this is an regular essential stage of completion of this path (sulook).
The explanation of this is that in the initial (part of this path) there is excessive enthusiasm and the natural desires are subdued. Towards the middle or the end (of this path) the enthusiasm wanes and the desires resurface. This is because the (sinful) desires are not eradicated (by spiritual struggle) they are only subdued. At this resurfacing spiritual struggle is again required. However, the hardship and effort in this (subsequent) struggle is to a lesser extent. لرسوخ التھذیب فی النفس۔ ., but determination, diligence, willpower and self control are required (to do so).
Based on the signs a sort of perfection is felt in (your) nisbet. Relying on Allah, I give you permission to take allegiance (from spiritual aspirants) (ijazet e bia’yet) and expect from Allah that it will be beneficial for the people. ‘
