Even though the soul is  metaphysical not  but like any matter, a soul also has certain properties.  In reality these properties are the faculties of a soul on which a soul functions. A soul consists of three properties. Mind, Intellect and characteristics. Mann Buddhi, and sanskar or habits

When a soul thinks it is called MIND. 

When a soul uses its decision making power it is called INTELLECT and 

when a soul repeats its behavior it makes CHARACTERISTICS.
