This test is conducted in between the third month of birth upto 2nd year. It is only during the first five months that new brain cells are procreated. Therefore, if this test is conducted in between 3 to 5 months, it is most effective in the long run. The grasping power of an infant is profoundly deep. Along with all other surroundings, the child readily picks up the thoughts in the mind of his parents in whose company it grows. In other words, the child becomes a reportoiry of 'good and bad' of its parents, the latter getting a priority in the normal course. Thus, in order to develop a child in 'clean' atmosphere, purification of thought pollution is inevitable. This post-birth test is therefore conducted on parents and it is through their reformation and elevation that the child potentially gets benefited.
