Premanand Maharaj Ji
How do I feel the same compassion for the old, the sick and strangers as I do for my own family?
See everyone as your own
Just as you feel love for your own young son, look at all sons that way, because until equal feeling toward all comes, the intellect is not considered pure. Do bhajan and plenty of naam jap, and serve animals and plants, seeing Bhagwan in them.
Then why not see all sons like your own son? Look, until an equal feeling comes toward all of creation, the intellect is not considered pure.
