By Swami Sivananda
Kachiyappa Sivachariar was a very fortunate bhakta of Sri Subrahmanya. He lived at Kanjeevaram 1100 years ago. He mastered all learning before his 10th year, and the Siva Agamas were his special study.
Lord Shanmukha, one day, appeared to him in a dream and ordered, "My boy, thou shalt sing a Tamil work and call it Kantha Puraanam, translating matter from the Sanskrit work, Sankara Samhita, and having for your first line,'Tigadachakkara-chemmukha-maindullan'."
Kachiyappa Sivachariar awoke and thought over this wonder, and thought over and over again, the kind commission accorded to him by his Lord. He took up the task and finished it suitably. When for recognition it was read before an assemblage of Pandits, some questioned his interpretation of the first line, God-given. Then God Himself inspired one and stated that the grammar for it could be found in Virasolliyam, a very ancient Tamil work. All wondered at this divine favour and declared the work authoritative.
