The formation of pa–ca-skandh?ú (r½pa, vedan?, saμj–?, sa×-sk?ra and vij–?na-skandha) analyzes the element of existence and consists of materials and hearts. The extension of r½pa-skandha widely includes bh½ta-bhautika so that our body belongs to r½pa-skandha and vedan?, saμj–?, sa×-sk?ra and vij–?na-skandha is relative to inside part of human mind. Therefore, we can understand that ?tman is composed of pa–ca-skandh?ú and ?tman has the sense of mutability. Both the beginning of an event and ending have their own reason and they break the idea of devotion of ?tman among the public.
Due to the analysis of dv?da§a-?yatan?ni (indriya-?yatana、visaya-?yatana), it is the function of our awareness for our sensation toward objective environment. Then, the consistence of a· ?da§a-dh?tavaú can carefully express the process of the beginning and the ending of worry. Among the system of a· ?da§a-dh?tavaú, it is the process of analysis for subjective awareness for objective environment. For example, eyes see something and we can see it. Consequently, the design of pa–ca-skandh?ú, dv?da§a-?yatan?ni and a· ?da§a-dh?tavaú is to help yogin to observe the recycling of everything among a systematic situation.
