He should recognise a spark of truth present in different views and attempt a synthesis of them all in order to arrive at the comprehensive truth. This theory of standpoints and their synthesis fosters intellectual tolerance and nourishes friendliness. Soul is the only sentient substance. Time, medium of motion and medium of rest act as the assisting causes of change, motion and rest respectively. Space acts as a universal container in which all other substances are contained.
Space is infinite.
All other five substances are eternally confined to a particular portion of the infinite space. The nature of soul is consciousness or sentiency. It expands and contracts according to the size of body it assumes in different births. It knows things, performs activities, enjoys pleasures, suffers pains, and illumines itself and other objects. All souls are inherently or potentially equal.
