“My dear Sanātana, although you are the deliverer of the entire universe and although even the demigods and great saints are purified by touching you, it is the characteristic of a devotee to observe and protect the Vaiṣṇava etiquette. Maintenance of the Vaiṣṇava etiquette is the ornament of a devotee.
