ISLAM: Tazkiya; Means of reaching God

Man is the creation and God is his Creator. As such, it is human nature that he should come close to God to the ultimate extent. But various things, such as pride, negative thinking, etc. separate man from God. Tazkiya aims at thoroughly purifying one of such negative feelings. The moment one detaches oneself from things other than God, one instantly feels that one has come as close to one’s Creator as it is humanly possible to come. One begins to experience the presence of God all around one.
The level of nearness to God depends on the level of personal realization of God. For instance, everyone is in need of innumerable things to survive in this world. But no human being is the creator of all these things. Someone else has bestowed them upon mankind, and God is undoubtedly that Bestower. God, the Supreme Being, is the only Giver. It is undoubtedly due to God’s unilateral blessings that one can exist in this world. If—even for a moment—this chain of blessings were broken, a person would no longer be able to sustain himself.
When an individual discovers God as His Benefactor, then quite naturally a fountain of love for God wells up in his soul. Then he becomes the embodiment of the reality described thus in the Quran: “Those who believe love God most.” (2:165). The Quran enjoins self-prostration as being necessary for nearness to the Creator: “Prostrate yourself and come closer to God.” (96:19)
What is this self-prostration? It is, in fact, the obeisance made by one who is filled with the love and fear of God: with these intense feelings, he falls prostrate before his Lord—this kind of prostration is as if a divine ascent for the believer.
