Conch also protects our intellect from ignorance-extremes arising within. It safeguards us from the external fear. That is why Guru śukrācārya presented Bali with a conch. In other words, the auspicious sound of the conch fetches us śukradaśe (good times).
We furnish our houses with all necessary comforts. However, there are more amenities in the bodily home created by the Lord. Just as an ever luminescent lamp, we have six sensory organs such as the auditory system. We have organs of action like the mouth that serve as servants. We have excretory organs to flush waste out of our bodies similar to the drainage system in homes. We have systems to carry fresh air throughout the body, like an air-conditioning conduit.
