Swami Mukundananda
Is seva only charity, or are there higher levels of service?
Three levels of seva: mind, body, wealth
Service is done with the mind, the body and wealth, and the highest is the mind. Hold the thought 'I wish to give happiness to God and Guru' and do your works with that intention.
The highest service is of the mind: to hold the thought 'I wish to give happiness to God and Guru,' and with that intention do your works.
