Buddha was the enlightened one, because it is said in the Dhammapada that "A unique Being, an extraordinary Man arises in this world for the benefit of the many, for the happiness of the many, out of compassion for the world, for the good, benefit, and happiness of gods and men. Who is this Unique Being? It is the Tathagata, the Exalted, Fully Enlightened One."

Sikkim is very renowned for abundant Buddhist Monasteries. It is said that Ashoka, the great Emperor of India is supposed to have sent an agent to the North and Sikkim was one of them. His main intention was to spread the message of Lord Buddha and make people embrace this religion so that life would become easy and more comfortable for them. It will enlighten them the truthful path of life, and bestow them the power obtain the proper means of livelihood.
Lord Buddha is said to be the direct descendant of God who came to earth much like Christ, in order to convince people to stay away from improper and unscrupulous means. The days of Buddha were full of conceited men who boasted on caste basis and this was something intolerable for the others, who ranked inferior to them.
So, there was a need for a separate religion where animal sacrifices and costly religious rites of the Brahmins were not compulsory. Lord Buddha born in a Kshatriya family, being a prince, came out one night tearing off his family bondages in search of enlightenment and he was successful. He was the right person who could teach humanity of the rightful path; so god selected him.
