The oldest proverbs have stemmed from ancient wisdom only. According to the ideals of Vastu Shastra, the cleanest doors and windows invite the most highly charged packets of energy. Spider webs, cocoon shells, insect nests are very common in and around the corners of doors and windows. This works most efficiently for bedrooms. Always look out for pigeon’s nests in the ventilators of your bedrooms as that is definitely a piece of bad omen!
