weak constitiution of mind and body comes from the effect of misplaced or negative influence from the 9 planets. There is a special ceremony were it can be counteracted and purified while worshipping those rulers of the planets. It goes along with Mantra Japa, different vratas (vows) and proper set up of the ceremony. One should not misunderstand that only the ceremony will be performed but one has to do also some kind of effort and spent time and dedication of this, that it works. Also in general there is a donation given to the purohit (priest) and the value for the ceremony is balanced by this. Please see under Donation the guidelines.
