Make yourselves into a garland and I shall be the thread holding all the flowers together. Consider yourselves the children of one mother, belonging to the human family. Do not give room for differences of race, creed and nationality. All belong to the caste of humanity, the religion of love and the language of the heart. The same object, water, is called by different names in different languages. Likewise, God is one, whatever the name that is used - whether Allah, Jesus, Buddha or Raama - have that faith. Don't criticize any religion. By developing this universalism, bring joy to Bhagavan.
