Yoga sutra 2.25
tad-abhāvāt-saṁyoga-abhāvaḥ hānaṁ tad-dṛśeḥ kaivalyam
As that (tad) misapprehension gradually reduces until it disappears (abhāvāt), the deep misperception (saṁyoga) between the “Seer” and the “Seeable” also vanishes (abhāvaḥ). When this happens (hānaṁ), the soul is completely independent from the mind and is totally free (kaivalyam).
Ignorance works like an undesirable weed in your garden of peace; you must deal with the roots/the root cause of the problem or else it will grow back stronger.
Elimination is achieved through regular practice of yoga.
Little by little, you see the light radiating from you brighter and brighter and it helps you see your true/spiritual nature more accurately. Ultimately, this may lead to liberation/enlightenment. It may or may not happen to you. The important thing is to focus on the process, the journey, rather than the results.
