Develop a mind of equilibrium. You will always be getting praise and blame, but do not let either affect poise of mind: follow calmness, the absence of pride.
With a genuine keenness or readiness to serve others, one can attain happiness in any group or community, and the eagerness to serve others will endow you with the power and skill necessary for the required service. Nowadays, we tend to regard it as derogatory to serve, but there is great worth in service.
As long as you have attachment to the body and attachment to objects, fear and suffering will be with you. Therefore Krishna told Arjuna to develop his discrimination and rid himself of body consciousness. Only then he would be able to develop integral vision.
The worthy person is grateful and mindful of benefits done to him. This gratitude, this mindfulness, is congenial to the best people.
