A seeker wrote, ‘I have an ailment of useless talking. According to my deficient understanding the reason for this is happiness. That is, whenever I am happy and there are no worries a sort of overwhelming euphoric emotional state develops. In it I speak a lot. Doing so gives me peace. Remaining quite is not possible for me. If I force myself to keep quite I get agitated soon. It is only with talking that agitation is removed, otherwise it stays.
This (useless) talking extends to the mentioning of obscene and back-biting. Until I do this my euphoric state does not normalize.’
Hakim al Umma Maulana Ashraf Ali Thanwi (Allah have mercy on him) replied,
‘The principle of treatment is to remove the cause of illness.
For this ailment the cause is euphoric emotional state. The removal of this is the treatment. This euphoria has to be subdued by its opposite. That is, contemplation and melancholy.
The thing that leads to the strongest level of contemplation and melancholy is death and what happens after it, like events in Barzakh, Day of Judgement, The Bridge (sirat) and the punishments for sinful activities.
Therefore, at the time of emotional frenzy contemplate about these events. If (you find) this contemplation is weak then read from a book on this subject. It is preferable that (in that state) you immediately withdraw yourself into solitude and reflect (muraqaba) or read (muta’la). This will treat the condition promptly.
If due to (general) emotional weakness reflecting or reading become painful secondary to overwhelming dread then reflect on the Prophetic sayings regarding mercy and optimism. This will maintain the balance. The real happiness, which is required as per (قل بفضل الله و برحمة فبذلك فليفرحوا ) will stay and the excessive euphoria, which has to be shunned (لا تفرح ان الله لا يحب الفرحين( will be eliminated.’
