To work without attachment is to work without the expectation of reward or fear of any punishment in this world or the next. Work so done is a means to the end, and God is the end.
The physicians of one class feel the patients and go away, merely prescribing medicine. As they leave the room they simply ask the patient to take the medicine. They are the poorest class of physicians.
Through selfless work, love of God grows in the heart. Then through his grace one realize him in course of time. God can be seen. One can talk to him as I am talking to you.
