ஸ்ரீ திருநாகேஸ்வரன் ஸ்வாமி திருக்கோவில் ( ராகு நவகிரஹஸ்தலம் - திருநாகேஸ்வரம் )

During the Samudra manthan, one of the best episodes in the Hindu mythology the asura Rahu drank some of the amrita (divine nectar). The sun (suryan) and moon (chandran) realized it and alerted Mohini (the female avatar of Vishnu). Mohini take off the asura's head before the nectar could pass his throat. The head remained immortal due to the effect of amrita and became Rahu. This immortal head from time to time swallows the sun, causing eclipses. Then, the sun passes through the opening at the neck, ending the eclipse. Lunar eclipse is due to kethu to swallows the moon on timely basis.

• The chief
