Earlier cultures were interested in the movements of celestial bodies as it was noticed that there were cycles in the power of sacred sites connected to the orbits of the sun, moon, planets and stars.
In this respect, certain sacred sites demonstrate regular periods of increase in their emanations of geophysical energies that seemingly correspond to the orbits of celestial bodies. In the case of Arunchala the moon has extraodinary relevance in both its new moon and full moon stages. According to the anthropologist Martin Gray:
'There is a great galactic symphony of subtle forces playing upon our planet by virtue of the cyclical orbits and particular positions of numerous different celestial bodies relative to the earth. The power places, because of their profound energetic resonance with different celestial frequencies, are ideal portals where humans may access those forces.'
