According to Prof. Dr Bhatt, 3 Fa colours are Red,
Orange, and Yellow, and Maa colours are Green, Blue, and
Violet. He has developed 6 Health Pyra colour plates and
a supporting plate with white colour. This is Health 9x9
and it is used as a pair for health and healing.
Normally, you use a single white plate. But appropriate
colour plate at the required location, and one white plate
on the opposite side can give better results.
