God almighty has invited you in the month of Ramadan to His banquet. As you see fasting is God's banquet; it is not like our parties with those formalities and lavish meals. It is a reception in which one should abstain from desires. Notice that one should perform the rituals in the holy month of Ramadan, particularly its mental rites. One should not be merely engaged in praying- prayer in its real sense is of importance. Remembering God in the real sense of the word is what brings tranquility to the heart.

(The holy Quran, 13:28) Remembrance of God means considering God present everywhere, in the holy month of Ramadan, one should be preoccupied with remembrance of God and His blessings and thank God for His favors.
