The fourth nadi of the heart leads to thoughtless awareness and innocence. The heart is the abode of the spirit and it is important to know more about it. There are four nadis in the heart and one of them leads to destruction if crossed beyond Mooladhara. To live in this world with innocence is a sign of purity. Desire is the second channel that can take you to destruction, and desirelessness is the only way to avoid aging, sickness, and worries. Everything created is made beautiful by Shiva's quality.
