In spiritual practice conversing with God has special significance because it is through this very medium that we get the spiritual experience of non-duality.
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.
