Contemplate in the background of your mind even whilst working. To do that, do not hurry, take your own time. Keep the remembrance of your real nature alive, even while working, and avoid haste which causes you to forget. Be deliberate. Practise meditation to still the mind and cause it to become aware of its true relationship to the Self which supports it. Do not imagine it is you who are doing the work. Think that it is the underlying current which is doing it. Identify yourself with the current. If you work unhurriedly, recollectedly, your work or service need not be a hindrance.
