I don't think, there is any word called "ভায়শ্ন" in bengali (As written by Mr. Pran Pratim). "Vaishno" is definitely a sanskrit word, the appropriate bengali of which should be "বৈষ্ণো". So the correct word for SVDK should be শ্রী মাতা বৈষ্ণো দেবী কাটরা (Shri Mata Vaishno Devi Katra). Kindly rectify it. (If you don't agree, then please copy this word "বৈষ্ণো", paste it in google and search.)
