The Aggregate of Volitional Formations (Saṃskāra-skandha)

Answer: Whatever is in motion and never still belongs to the aggregate of formations (saṃskāra). This includes both body and mind, but in fact bodily movement is also movement of the mind consciousness; if the mind consciousness does not move, the body cannot move. The transmission of the object-aspect is also movement, arising from the movement of consciousness. If these movements cannot obscure one's own cognition that accords with principle and accords with the Dharma, so as to discern the true nature, and one only recognizes the moving marks of formation, then these movements are the aggregate of formations (saṃskāra); otherwise, they are simply the aggregate of formations (saṃskāra-skandha).
