We notice innumerable matter (Padartham) on earth, the matrial world, Prakruthi. Matter is energy. Energy is particle (Kanam) as well as waves. Particle moves in Quantum (Kettu). Movement of energy is in the form of Vibration (Spandanam) which is everywhere even in space and vacuum (Shoonyatha). Theory of Einstein and Quantum theory explain all these fundamentals in Modern science. But we are only familiar with science of material world explained in Classical science of Newtonian age which does not describe about vibration of energy.
Every Kavu has a legend that describes as to how and why legendary Heros or Deities are worshipped. According to particle theory of Modern science, the Kavu is powerhouse of energy. Kavu is an energy rich field (Kshetram) consisting of Boson and Psychon (energy particles). If you visit Kavu especially at the time of Kaliyattam, you will feel Vibrant and energetic, no matter whether you worship or not. Ezhome has the abundance of 55 Kavu which shows that Ezhome itself is a source of energy, a powerhouse.
