According to Jainism, thoughts arise due to the interaction of the soul (jiva) with karmic particles (karma). The soul is naturally pure, endowed with infinite knowledge, perception, bliss, and energy. However, due to its association with karma—subtle material particles attracted by passions, desires, and activities—its qualities are obscured.

When the soul engages in activities such as thinking, speaking, or acting, it attracts and binds new karmas. These karmas can influence the mind, resulting in the emergence of thoughts, emotions, and desires. In Jain philosophy, the mind (manas) is considered a subtle material entity that interacts with the soul, serving as an instrument for thought and cognition.

Thus, in Jainism, thoughts come about due to the interplay between the pure soul and the karmic matter associated with it. By practicing right faith, right knowledge, and right conduct—collectively known as the Three Jewels (Ratnatraya)—one can reduce and ultimately eliminate karmic influences, leading to greater purity of mind and clarity of thought.
