Premanand Maharaj Ji
How many hours should a doctor work to earn money, and how should fees be handled?
Charge the rich fully, ease the poor
Do not make money your priority; ease the fees of the poor, who feel even a small sum deeply. Serving the patient as Bhagwan brings His grace, which gives happiness, not money.
From those who are wealthy and well-off take the full account, but give some concession to the poor, keeping the aim of earning less yourself.
