Greetings and Namaste. As per Hindu Traditions all full moon days (Pournami) are very important from the religious point of view - as it is they day when manes (Pitrus) and Devas are worshipped - for example Satyanarayana Puja, Devi Puja, Shiva Puja are performed. In the South, Chitra Pournami is a very important occasion where Lord Shiva is worshipped along with Chitragupta who is the book-keeper of all our deeds and mis-deeds (to be benign when we pass off his mortal coil and go in front of him for the balance sheet of this life)
In that context, I happy to attach a beautiful hymn on Lord Somanatha (Somnath in Gujarat, known as Prabhasa in puranic times) taken from Skanda Puranam, Prabhasa Khanda, Prabhasa/Nyankumati Mahatmya, Kubera Nagarotpatti and Chapter 290. The hymn is easy to understand and essentially extols Lord Somanatha as the Mula Prakriti. I think the prayer is especially beautiful from the Sharanagati perspective - it beseeches Lord Somanatha to redeem the reciter from Samsara and its tribulations.
May We Seek The Blessing of Lord Sadashiva on this Chitra Pournami day!
