In plain words
13. The heart must be immersed in God, the hand in work
The physical object must be your servant; you must not be the servant of the object
Students! By your own human effort, find the Ancient Person who stands beyond delusion and darkness. You were born heirs to the state of eternal Ānanda. You are God's darling children. You are supremely holy; do not think of yourselves as sinners. You are lion cubs, not sheep. Think of yourselves as drops of nectar. You are not physical objects; the physical object must be your servant, and you must not be the servant of the object.
