When a person is accustomed to doing good and practices it consistently, feelings of jealousy, envy, anger, and other negative emotions will not reside in their heart. And if the heart is too often afflicted with 'illnesses,' it can lead to mental distress. Fasting, specifically during this month of Ramadan, is a timely and opportune moment. Why? Because it is a state for self-training and purifying the soul to become a person with a better personality than before.
Individuals prone to emotional instability, who struggle to express or suppress their emotions, and are sensitive, will find tranquility during Ramadan. Ramadan, this blessed month, can make people realize and remember to always be grateful and do good. Arief Wijaksono, a psychologist from the University of Indonesia (UI), agrees that fasting can nurture the soul and control people's emotions.
This is because religion teaches the suppression of desires, which helps control various 'heartfelt ailments,' and through fasting, stress or the intention to violate norms/rules can be curbed and overcome. However, fasting should not depend solely on religious leaders or 'ustads,' where it is observed only after being advised. This leads to a lack of direct interest in learning the Quran and fosters a pragmatic attitude.
It would be better understood by striving to comprehend directly from the source, making worship more sincere, thus leading to healthier mental/spiritual/psychological well-being. Especially when accompanied by good deeds, which will undoubtedly be multiplied by God. Source: Khazanah Ramadhan Republika page 30, Friday, July 11, 2014, 13 Ramadan 1435 H.
