First, the knowledge of different subjects like the color, form, etc. and their related aspects is done through Shruta Jnana. The knowledge of meaning that is gained by reading and listening to scriptures is also called Shruta Jnana.
Although the origin of Shruta Jnana, like Mati Jnana, also requires the help of mind and senses, there is a difference between the two. Mati Jnana is directed towards existing objects, while Shruta Jnana is directed towards the three periods of time: past, present, and future.
Besides the difference based on the subject, there is also a difference in that Mati Jnana does not involve verbal expression, while Shruta Jnana does. This means that Mati Jnana is what is not born from the womb, i.e., not born from a mother. Like Mati Jnana, Shruta Jnana is also produced by the senses and mind, but in Shruta Jnana, the mind is more important than the senses. The senses only perceive the tangible, but the mind perceives both the tangible and the intangible. In reality, it is the mind that contemplates and thinks; as it is said, "Yathamanagmanah." The mind also contemplates the subject matter perceived by the senses, and sometimes it contemplates independently. It is also said, "Shrutamanindriyasya" (Tattvarth Sutra A. 2. Su. 20), meaning that Shruta Jnana is primarily the subject of the mind.
Avadhi Jnana is the knowledge of the form, meaning, and tangible substance that is obtained solely through the soul, without the need for the mind or senses.
