Abrasives are extremely commonplace and are used very extensively in a wide variety of industrial, domestic, and [[technological]] applications. This gives rise to a large variation in the [[physical]] and [[chemical]] [[composition]] of abrasives as well as the [[shape]] of the abrasive. Common uses for abrasives include grinding, polishing, buffing, honing, cutting, drilling, sharpening, lapping, and sanding (see [http://en.wikipedia.org/wiki/Abrasive_machining abrasive machining]).  [http://en.wikipedia.org/wiki/File_(tool) Files] act by abrasion but are not classed as abrasives as they are a shaped bar of metal. However, diamond files are a form of coated abrasive (as they are metal rods coated with diamond powder).[http://en.wikipedia.org/wiki/Abrasive]

Never be [[afraid]] to go to the stone and make [[sparks]] in your endeavor to pursue the polished edge which you seek. It may only be [[attained]] through the grinding away of the unnecessary in order to [[achieve]] the [[point]]. [[Effort]] must be put forward, and you know you are making [[progress]] when the sparks are flying.

Cause the [[sparks]] of [[spirituality]] to fly. Do not fear that this is [[radical]] or too [[intense]], as this is exactly the [[step]] to be taken in order to achieve the results. Don't [[shy]] away from the apparent ''abrasiveness'', as you have come to [[realize]] in your own [[spiritual growth]] the benefits of the effort are far in excess of the apparent harshness of the [[process]].- [http://nordan.daynal.org/wiki/index.php?title=2001-06-10-Patterns_of_Duality#Cooperation Malvantra]
