Performing ritualistic worship as per Path of Rituals (Karmakand) is at the gross level, whereas doing so in the mind, is at the subtle level. Based on the principle of Spirituality – ‘one should go from gross to subtle’, worship performed in mind (subtle) is superior to ritualistic worship performed physically (gross).
Saint Tukaram Maharaj says in one of His hymns, “A devotee’s duty is to have singular bhav towards God. The true secret of devotion is to have this bhav with a firm resolve constantly. Devotees should have firm faith in God, without expecting anything in return. They should not wish for the support of anyone else. God should be their sole support.
