Kandar Anubhuthi is a collection of songs sung by the great Tamil Saint Arunagirinathar when his soul was in parrot's body. The collection of songs were sung during the period 1400-1500 AD. There are 51 songs including the Kappu (Requesting Lord Ganesha to give the blessing to sing a complete collection of song ). Each song is dedicated to Lord Muruga and most songs has a similarity of 2 lines praising Lord Muruga and the remaining 2 lines requesting lord to grant true wisdom to overcome the Maya.
Kanthar Anubhuthi is a deeply philosophical and spiritual treatise with profound mystical import of Saint Arunagirinathar, who stands unique among the devotee-saints of the Tamil Nadu.
Kanthar Anubhuthi is a work of 51 verses. It is held in high esteem as a Mantra-Sastra and as the crowning glory of Sri Arunagirinathar's works, because of its high spiritual value and depth. The verses are short, rather the smallest in all the works of Arunagirinathar, but they are the most sublime. As the title suggests, it is a work on (the attainment of) God-Experience. There are certain editions of the Kanthar Anubhuthi with 100 verses, but the last 49 verses are generally rejected as later additions by someone and not Arunagirinathar's words.
"Kantha," in Tamil, is "Skanda" in Sanskrit; it is one of the names of the spiritual Son of Lord Siva. Some of Skanda's other names being: Shanmukha, Karttikeya, Guhan, Velayudhan, Murugan, etc. He is the younger brother of Lord Sri Ganesha.
"Anubhuthi," is rather a Sanskrit term used in the Tamil language as well in the same sense, i.e., direct or immediate Experience of God, and it denotes the spiritual union of the soul with God. It usually implies the highest non-dual or Advaitic realization. It is Sakshatkara or direct experience. Hence, Kanthar Anubhuthi would mean the Immediate or Direct Divine Experience of Lord Skanda. And, to Arunagirinathar, Lord Skanda is not merely a personal deity or Ishta Devata but the Supreme Absolute Itself, as he himself reveals in many verses, particularly in verses 2, 13, 28, and 49. Hence, we may say that "Kanthar Anubhuthi" means, in simple terms,"God Experience."
