So far as you working engagement is concerned, certainly you are not a karmi. Any person whose constant occupation is Krishna Consciusness, he is not a karmi, he is a devotee in all circumstances. You should accept the best source of monetary income and use it for Krishna. That is better sannyasa. Stick to your job and use it for Krishna Consciusness. You are not karmi.
Letter to Gopal Krishna April 4, 1971
