Most people of Nepal are Hindu (>80%), the remaining population is Buddhist, Muslim, Shamanist/Animist, Jain , or Christian. The people of Nepal are very tolerant of other religions and the blend of Hinduism and Buddhism makes it sometimes difficult to clearly identify if something is one or the other.
Buddhist stupas, Buddha eyes (like image above), prayer flags and prayer wheels are displayed throughout the country. Boudhanath in Kathmandu is one of the largest stupas and one of the holiest Buddhist sites. And probably most importantly, Prince Siddhartha Guatama was born in 560BC in Lumbini, Southern Nepal. He became what most Americans know as Buddha. (FYI, there has been more than one Buddha and he was also not the first.)
My knowledge and spiritual path is greatly influenced by Buddhism; as it is not a religion but a personal journey to enlightenment. And my knowledge of both Hinduism and Buddhism grew as I studied yoga. I am very excited to experience the culture that is influenced by these religions and to add my prayer flags to Thorung La pass to spread good will and compassion to all.
