🌕 What is Pournami?

Pournami is the full moon day (பௌர்ணமி), considered sacred across all Hindu traditions. In Tamil Nadu, it is seen as the perfect day to:

• Visit ancient temples like Thiruvannamalai, Chidambaram, Kanchipuram, Rameswaram

• Perform Girivalam (circumambulating Arunachala Hill)

• Observe fasting (viratham) and chanting mantras

• Offer Arghya (water offering) to Chandra Bhagavan (Moon God)

The moon is associated with mind (manas) and emotional healing in Tamil spiritual thought. Thus, Pournami is ideal for cleansing emotional karma.
