It is said that we cannot experience true joy while others are suffering. In the Osashizu is the following verse:
The mind of saving others is the real truth of sincerity alone and, by this truth of saving others, you are saved. December 20, 1889
If we go throughout life helping others, and eliminating greed, arrogance and self love from our minds, then God will take care of us. Do you have this true sincerity to rely on God?
