The special pooja is performed every month on full moon day at around 5 PM . The main homam performed for this is the Sudarshana homam which brings immense gratification to the devotees performing it. The Sudarshana Chakra (the discus of the lord) is the one that always protects his devotees. It is the main weapon (astram) adorning Lord Vishnu in all his 10 incarnations. The Sudarshana Chakra is the one which is known as the Chakrathazhwar. Devotees performing this pooja will overcome their difficulties and will be blessed with wealth, prosperity, progeny and happiness in their family.
