So if you kindly issue a general letter, suggestively reading as follows:
"Certified disciple of Swami A.C. Bhaktivedanta, the missionary preacher of Vaisnava cult in the Western world, is strictly following the Vaisnava regulations. They are regularly initiated in Vaisnava culture. They have changed their names in the form of Krsna das or servant of God, and are following the regulative principles very strictly, worshiping the Lord in the Temple, and thus they are converted Vaisnavas in the strict sense of the term. No Temple authority of India should therefore restrict them in the matter of offering their respects to the Deities or chanting the Hare Krsna Mahamantra within the vicinity of the Temple."
Of course each and everyone of my students will carry an authorized certificate of initiation and if it is accompanied by a copy of letter as above mentioned, I think that will be a great satisfaction for me.
