Purnam means perfection, wholeness and fullness; the full moon is called Purnima. Purnam is the unchanging perfection of the source of our life, the essence of our existence and the purity of our clear awareness. Purnam is always present in us, just as the moon is always fully present even though it appears to change. Our daily experiences are in continual change and flux, but the perfection of our being remains forever constant.
Awareness of our own perfection can be remembered during meditation when we rest in the awareness of our essence that never changes. Simply sit with your eyes closed, and watch. You will notice a variety of sense experiences and thoughts come and go in your mind. Keep your attention on the space between these thoughts where your mind is still and clear. This space is your own unchanging and perfect being.
