"Many are the names of God and infinite the forms through which He may be approached." -Ramakrishna
Sri Ramakrishna was a 19th century Indian mystic. He was Hindu priest who worshiped the goddess Kali (a form of the god Shiva associated with eternal energy).
However, Ramakrishna also practiced both Christianity and Islam. His beliefs all centered around one basic concept...
All religions lead to the same God
"God can be realized through all paths. All religions are true. The important thing is to reach the roof. You can reach it by stone stairs or by wooden stairs or by bamboo steps or by a rope. You can also climb up by a bamboo pole."
A movement and entire school of thought was spawned based on Sri Ramakrishna's teachings.
His name is a combination of the god Rama and Krishna - both avatars of the Hindu god Vishnu.
He was a clear supporter of harmony between all forms of faith and cultures.
