A'maal are the objective, not feelings.

 Condition: Hadrat, in addition to offering salâh, keeping fast, etc. I try to abstain from all sins. However, I am doing all this as a habit. I do not have love for Allâh, desire for Paradise, fear of Hell, and consciousness of the difficulties of death and the grave. 

I also do not have love for my shaikh. I occasionally experience this condition, but do not most of the time. I desire not be heedless of Allâh Ta’ala for a single moment. I conduct Hadîth lessons after the fajr salâh and fiqh lessons after the ‘asr salâh in the Masjid in which I am the imam. The musallîs (those who come to the Masjid for salâh) sit regularly for these lessons. 

Answer: To fulfil acts of worship as a habit is proof that you are doing them out of love. If – Allâh forbid – you leave out these deeds, it will be destructive. If the teachings of Hakîmul Ummah Thânwî rahimahullâh are before a person, he cannot go astray. 

Hadrat says: “(A'maal)Deeds are the objective, not conditions/feelings.” There are different colours for love and fear. A person has love but does not feel it. Therefore, if he does not feel this love, it does not mean that he has no love. 
A person’s condition does not remain the same all the time. Conditions change constantly. You should therefore not become uneasy when conditions change. Remain constant on deeds. Progress is made through deeds and not conditions.
