I am glad that ya brought this issue.We nepali have some kind of confusion about this issue and the best way to look ourselves is to understand where we come from. We were born hindus and Hinduism is an enthical religion i.e it differs in different places. more over,its the way of life. In hinduism, we arent obliged to perform any rituals on a regular basis or a weekly basis but we do have lot of religions. what ever we do revolves around our religion.I donn consider myself religious person but i realized that what ever i do is based on our religion. for an instance, tradition of tika,tradition of bowing to our elders. think we might  forget our religion once we come here but it wont be easy.
