The moon is considered the kind of herbs and medicines and is a very powerful healer. This is why in India the medicinal herbs were always planted and harvested at appropriate phases of the moon.
This mantra honours the moon as the guardian of the healing plants and can be effective in healing us from some simple illnesses.
Listen to it about 24 times, each night when the moon comes out. Fold your palms and place it near your heart and visualize the moon in your heart when you listen to it.
oṁ somāya namaḥ
