Master Lin's describes the six-word chant as follows:
ONG - means the heart of wisdom. This is the wisdom of the universe.
MA LEE - means a person's heart, which is full of changes.
BAE MAE - means the purity of the heart, the emptiness.
HONG - means the enlightenment of a person with the wisdom of the universe, or with the power of God.
Hope this helps - oh and each of the sounds of the chant also helps with problems. For example:
ONG - can help with problems in the eyes, the ears, nose, and all kinds of headaches and head problems.
MA LEE - can help with problems in the throat, shoulders, elbows, and the heart and lungs.
and so it goes on. Sounds are energy just like everything else, and they can help you go into the emptiness faster and deeper.
With Love
