One of the commandments of the Quran is given in these words: “Believers, remember God with much remembrance.” (33: 41) According to this Quranic verse believers must remember God very much, every day and every moment. This is the greatest teaching of the Quran, and it is the highest form of worship. One who does this will be blessed with the greatest reward from God Almighty. What is meant by ‘much remembrance’ of God? Remembrance does not refer to the repetition of some words, but it is in the sense of thinking. Much remembrance, or zikr-e-kathir, is not a kind of lip service. It is rather a high kind of intellectual activity and a sign of God realization. Remembering God much, is a result of a chain reaction in the thinking process; that is, a series of thoughts in which each thought causes the next one. Zikr-e-kathir, or much remembrance, is a result of creative thinking. It is a product of a prepared mind. If you possess a prepared mind, then your mind is bound to get activated at every experience or observation. You will start discovering one aspect of God-realization after another. In this way a chain reaction will be initiated in your mind.
