1. Read Narottama dasa Thakura’s Prarthana

    Narottama dasa Thakura says, gauda mandala bhumi, yeba jane cintamani tara hoy vrajabhume vasa. Anyone who understands gauda mandala bhumi in Bengal — this Navadvipa, Navadvipa-candra, Sri Caitanya Mahaprabhu — if anyone understands the spiritual value of this land, he lives in Vrajabhumi, in Vrndavana. There is no difference between Vrndavana and this Gaura-mandala-bhumi. That is the verdict of the sastra. Gauda-mandala-bhumi yena jane cintamani tara hoy vrajabhume vasa [Srila Narottama dasa Thakura].

    So read Narottama dasa Thakura's Prarthana, Bhaktivinoda Thakura's Prarthana. They are very, very valuable for advancement of spiritual understanding, especially Narottama dasa Thakura's Prarthana. So, by reading them, by understanding them, we can understand Krsna very easily. Otherwise, it is very, very difficult to understand Krsna.
