Prayer is the sign of devotion. It includes respect, love, pleading and faith. By praying a person expresses his helplessness and surrenders to the Master (God) and pleads for help. It is the connecting link between Master (God) and the self.
Many people generally pray with specific motive based on the belief that if you pray sincerely you would get what you pray for. People pray for many reasons such as personal benefits or for the sake of others. An average person mainly prays to God when he is unable to face difficulties in his life.
Prayer as a method of worship is common in every religion. It may involve the use of words of praise or songs by an individual or group of people. The people who pray about some worldly benefits like job, money, power, etc. and some other requirements like recovery from illness, happiness etc., are generally in the initial stage of their spiritual journey. Prayers of spiritually progressing persons are without worldly expectations, but there is also some sort of pleading to GOD for spiritual progress and for removal of obstacles in their spiritual practice, reduction of their ego etc.
