1. Narottama dasa Thakura on the qualification to see Vrndavana

    Our present position is that we are materially diseased, so we have to become free from the material disease. Material disease means sense gratification, and the most formidable disease is sex. This is called material disease. So visaya chariya. We have to be…, become free from the contamination of visaya, material enjoyment. This is the statement of Narottama dasa Thakura.
    visaya chariya kabe suddha ha 'be mana
    kabe hama herabo sri-vrndavana
    "When my mind will be cleansed of all material desires, then I shall be able to see what is Vrndavana." It is very difficult to see Vrndavana with material desires. Bhakti means the first qualification is to become free from all material desires.
