There are said to be five stages of reflecting upon personal form of God- Dhaarna, dhyaan, dhruv smriti, svaroop chintan and samadhi. It starts from taking His form as a particular figure which may be Lord Ram, Lord Krishna, Lord Shiva, Devi Durga and like. Second step is to hold the same figure inside our body and attentively focus on it. 'Naam sankirtan' scientifically helps in strengthening this practice of concentrated inner visualization as the centrifugal force of the sound waves throws the wandering thoughts away and the gravitational force of the devotional words makes our heart feel His touch.
