On the last day of the lunar 7th month, one of my student did a 烟供 for all sentinent beings, bringing the wandering souls back to the place where they could cultivate and recarnate.
Lunar 7th month is never a month meant for burning of joss paper for deceased. Would you want your deceased family/friends to continue staying in hell or wandering around as a wandering soul with lots of ‘money’? I’m sure you would very much prefer them to be in a better place where they could continue accumulating merits and get out of the samsara.
烟供 is the compassionate way to treat all suffering souls; not the burning of joss paper. 烟供 can be done by anyone with the correct procedure and of course, it brings much merits to the one doing the 烟供.
