Explanation:

Guru Nanak moved by the plight of the people of world wanted to tell them about the "real message of God". The peoples of the world were confused by the conflicting message given by priests, pundits, qazis, mullahs, etc. He was determined to bring his message to the masses; so in 1499, he decided to set out on his sacred mission to spread the holy message of peace and compassion to all of mankind.
