The flame height is to be adjusted so that it is just below the top camphor containing receptacle. Where there is a lot of negative stress energy in the atmosphere, the device attracts it and burns it and this can be seen as a black carbonized 'beehive'type of structure that grows below the camphor receptacle.

As the atmosphere in the area purifies (over a few days), you will find the beehive structure no longer appears, even if the flame is very close to the camphor receptacle. This is evidence that the beehive does not grow because of incomplete combustion as one may be led to think!

The black carbonized negative energy should not be touched by hand. After removing any residual camphor and reserving for future use, wash the receptacle in running water and clean with a good detergent. Dry off and use as before.

Another observation regarding the evaporation of the camphor: Where much negative energy exists, the odor of evaporating camphor is very less or even absent. As the atmosphere cleans up, the camphor smell returns. You will experience this feedback through the Grandmaster's specially empowered "PURITY YANTRA"
