I have already mentioned about this Mantra in my previous letter and I beg to confirm it further that the Name "Krishna" even up to the foreign words like God and Allah, if they at all aim at the Supreme Personality—then the Name is as much holy and potential as perfect is the Supreme Lord—because in the Absolute Realm or Spiritual Nature everything is identical with everything as all of them are qualitatively spiritual and therefore pure, eternal, liberated and perfect.
For all practical purposes if we systematically preach to chant the holy name of Godhead, I think no body even the religious fanatic will take objection to it. Every human being has a conception of the supreme truth. That conception is presented in some concrete shape. If therefore the Mussulman or the Christian denies to chant the name of Rama or Krishna we may ask him to chant the name of Allah or God respectively and I think therefore there will be no objection even by the Buddhists if we simply ask them to chant the name of Lord of Buddha in the systematic way.
The systematic way means to avoid the ten different offenses in the process of chanting, which are all philosophical truths.
