My point of view:
In ancient time, the sovereignty of any country usually used to emanate from Kings or God Kings and therefore "religion" and "state" were closely knit. The remnant of such historical linkages were tuned to Nepalese political system till our recent memory. However, time has changed now. We suggest some our near and dear friends to think twice or thrice before we preach for a religious state !!
In the preamble of our draft constitution, it states the sovereignty of our country emanates from the power of Nepalese people of all caste, creed, religion or ideology or gender.
We need to separate "religion" and "state" since they do not go along well together. What we need to do and work hard in order to glorify any religion of what you faithfully believe, we need to empower people with "just society" then harmony will prevail and there will be no intrusion from anything you consider foreign !! Nepal is a great country with ancient heritage from where "Sana-tan" , Jain, Buddha "dharma" and even other local "shamanistic" practices matured !! We need not forget our root. Only we fear when we do not have confidence in ourselves then we talk of something "abstract". Hope we do not talk of "abstract and hypothetical" gibberish while we forget pragmatic solution for the people and by the people.
