## Description of Mind Purification
**Chapter Four, Light of Yoga, Verses 45-48**
In these six Leshyas, the first three are considered unfavorable (A-prashasta) and the last three are favorable (Prashasta). As the soul becomes purer and purer, the Leshyas change. The soul attains a state of existence based on the Leshya it experiences at the time of death. Therefore, the Lord said, "Jalle se marai, talle se uvvjai." This means that the soul is born into the same Leshya in which it dies. Similarly, the Bhagavad Gita and other scriptures say, "Ante cha Bharat Shreshtha! Ya matih, sa gatir nrunam." This means that the state of existence of humans is determined by their final thoughts. The word "mati" used here refers to consciousness. How can the statement "As the thought, so the state of existence" be consistent? If the meaning of "mati" is taken as the result of the most impure state, then the statement of the great sage becomes logical.
Of the six Leshyas, a soul in the Krishna Leshya goes to hell, a soul in the Neel Leshya goes to the state of stationary beings, a soul in the Kapoth Leshya goes to the state of Tyancha, a soul in the Peet Leshya goes to the state of humans, a soul in the Padm Leshya goes to the state of gods, and a soul in the Shukla Leshya attains liberation. What more can be said? By abandoning the impure Leshyas and accepting the pure Leshyas, the mind can be purified progressively.
**Some scattered methods of mind purification are described as follows:**
**Verse 45:**
**Meaning:** To purify the mind, one should control attachment and aversion, which are the forms of liking and disliking. If attachment and aversion arise, they should be rendered ineffective. By doing so, the soul, free from impurities, resides in its true nature.
**The difficulty of controlling attachment and aversion is explained in three verses:**
**Verse 46:**
**Meaning:** Even those who strive to control their minds, like yogis, are overcome by attachment, aversion, and delusion, which make them foolish and hateful, and bring them under the control of these vices.
**Verse 47:**
**Meaning:** Even while protecting their minds from vices through Yama, Niyama, and other practices, yogis are constantly deceived by attachment, aversion, and other vices, like demons. Just as demons, despite being controlled by mantras and other practices, deceive practitioners when they get an opportunity, similarly, attachment, aversion, and other vices deceive the minds of yogis.
**Verse 48:**
**Meaning:** The mind of a yogi whose knowledge and vision are destroyed by the darkness of attachment, aversion, and other vices is dragged into the well of hell, just as a blind person drags another blind person into a well.
**Meaning:** Darkness covers the light of the eye; similarly, attachment, aversion, and other vices cover the light of the soul's true knowledge and vision. When the knowledge and vision (faith in the truth) of a practitioner are destroyed, the mind, corrupted by vision and knowledge, brings him under its control and throws him into the well of hell. Just as a blind person throws another blind person into a well, similarly, the mind blinded by attachment, aversion, and other vices throws a mentally blind person into the well of hell. This means that a person who is blind to his mind falls into the well of hell.
**Here is the meaning of some internal verses written on this topic:**
Desire, liking, delusion, or attachment to material things is called attachment, and aversion, dislike, hatred, or jealousy towards the same is called aversion. Both attachment and aversion are great bonds for all living beings. They are considered the root and trunk of the tree of all suffering. If there were no attachment and aversion in the world, who would be surprised and delighted to see happiness? Suffering...
