(bheda) means division. It is of six kinds :
35c57-auf-aus-aforcat-T eafa cena 11293 Urkara--Effecting separation as in sawing a piece of timber. Curņa-As the grinding of wheat into powder. Khanda-As the separate parts of a broken pitcher. Cürnika–As the separation of chaff from rice or pulses. Pratara-As the separation of layers in a sheet of mica. Anucajana--As the smithereens of a blacksmith's workshop.

The production of shadows is also correctly explained as due to the obstruction (avarana) of light.
Lastly the division of light energy into two categories; ätapa and udyota, is based on scientific considerations : ātapa is the sunlight or light of a fire, or electric lamp, etc., and
