What is the significance in performing TharPanam during eclipse?
During lunar eclipse, the polar rays of the sun reaching the twilight zone of the moon,which is but the edges of Full moon, are obstructed by the earth, thereby bringing some contact to that part of earth, though on night side, with the polar rays of the sun. Then that part becomes conducive for getting into a link with pithru lokam through thetarpaNam offered. The timing of tarpaNam during eclipses, like soon after the beginning or after starting to leave etc. can thus be related to the obstruction to polar rays of the sun by moon or earth. The usage of Kush Grass, known as Kusa, Dharbam or Dharbai during this time of GrahanaTharppaNam i.e. Solar – Lunar Eclipses, prevents the radiation passing into ones body.
