In the Philosophy of Buddhism，the three concepts of "Skandha","Ayatana" and "Dhatu" are the fundamental and important concepts.
The contents are:
The five skandhas (aggregates) include form (matter)，perception，conception (idea)，volition (will) and conciousness. The twelve ayatana include six sense organs and six sense objects. The eighteen dhatus include six sense organs, six sense objects and six senses. I explained，discussed and illustrated these concepts. Finally，I attained conclusion，that is to say,"Skandha"，"Ayatana" and "Dhatu" are no substance (anatma)，no duration (anitya) and no bliss (duhkha) except Nirvana.
