virameta yada cittam
hitva vrtti-trayam svayam
yogena va tadatmanam
Either automatically or because of one’s regulated spiritual practice, one’s mind may stop functioning on the material platform of waking consciousness, sleep and deep sleep. Then one understands the Supreme Soul and withdraws from material endeavor.
As stated in Srimad-Bhagavatam (3.25.33), jarayaty asu ya kosam nigirnam analo yatha: “Bhakti, devotional service, dissolves the subtle body of the living entity without separate endeavor, just as fire in the stomach digests all that we eat.” The subtle material body is inclined to exploit nature through sex, greed, false pride and madness. Loving service to the Lord, however, dissolves the stubborn false ego and lifts one to pure blissful consciousness, Krsna consciousness, the sublime perfection of existence.
