Burning Kesh

I'm sorry if this may be a stupid question, but why should we burn our kesh when it comes out while we comb it? Is it written in rehatnameh that this is what should be done? I was not sure of how to dispose my kesh, and so I have collected it for a while. If we should burn it, then what is the best way to do so? and what should be done with the ashes?

There is no such thing as a stupid question.

As per your query, our kesh are a sharomani ang (highest).
If we're to consider disposing them in other ways, we would probably throw them in the garbage.
How can a gursikh's kesh go in such place? Even when they are bird and fallen.
Hence, the same concept is applied here, that would be applied to doing agan bhet of gurbanee angs.

Best way of doing it is weekly or monthly, however it seems convenient to you.
Collect kesh in a paper bag or a white rumalla (daas's way)
At the end of the week, daas does a small ardaas, and does agan bhet of kesh.
I'm from toronto, so I do it inside my garage in the winters. It's too moist outside.
After that, I ask muaafee for any beadbee. I collect the ashes and pour them into the ravine behind my house.
The above is what I have been taught by gursikhs.

Vaheguroo jee.
