In English
For example, a piece of dark charcoal cannot be whitened by either rubbing it with soap or rinsing it in milk. But both soap and milk turn black due to the company of the black charcoal. So men have to conduct an investigation to find out how charcoal becomes white. Charcoal, which was once a piece of wood, turned black due to its unfinished purification in the fire. It neither enjoys its natural state nor its finished state. Since it is in the middle state, it is marked by impurities. It is only by throwing charcoal into fire, and exposing it to the full heat of burning flames, that it can be whitened. It is only by exposing it to the ordeal of fire that the charcoal becomes white and bright. The white ash which ultimately remains is worthy of worship and is applied as (sacred ash) on the forehead.
