What is Islam concept on merging oneself with God?

"'The concept of merging with God is not a right concept. The creature cannot merge with the Creator, because they are two different entities. The right thinking is that one should yearn to become spiritually, not physically, close to God. This kind of experience is quite possible. The method of attaining this is contemplation. When you read the scriptures and other relevant literature, also when you observe the world around, you will discover the Creator of the world. You will find the signs of the attributes of the Creator in nature and creation. This kind of contemplation makes you closer and closer to God, until you feel that you have found God, you are living in His neighborhood, and you are receiving inspiration from Him. This is realization of God, and it is quite possible for a human being to attain this God-realization."
