Appaya Dikshita got the name Vinayaka Subramanya after the Namakarana or naming ceremony. His guru Rama Kavi gave him the teachings of the Hindu scriptures. At a very young age, he completed the fourteen Vidyas. After attaining his education, Appaya traveled far and wide and entered into philosophical disputations and controversies in many centres of learning. He flourished under the patronage of the kings of Vellore, Tanjore, Vijayanagar and Venkatagiri. He was an Advaitin and did not differentiate between Vishnu and Siva. This is evident from his composition 'Sivarkamanidipika' in which he praises Siva and again his poem 'Vardarajasthava' and 'Krishna Dhyana Paddati' shows his love for Lord Vishnu. It is also said that he composed a hundred verses on Nataraja i, e, on Siva and 'Govindaraja' i, e, Vishnu, which are preserved in the same temple-complex in Chidambaram. He tried to end the controversies between the Vaishnavism and Saivism schools of thought and harmonise both the schools. He dedicated his heart and soul in this work and served several years to make it successful. He was warned by a group of people personally to stop this but he did not fear at all and continued the good work with more courage and faith.
Appaya Dikshita wrote the 'Kavalayananda', a work on Sanskrit poetics on the request of his patron king of Vijayanagar Venkata II. The ruler of Velur, Chinna Bommu Nayaka also offered his patronage to this great scholar. It is believed that the Nayaka bathed Appaya Dikshita in gold (kanakabhishekam) in appreciation of his intellectual scholarship. He was a regular visitor of the court of the Nayaka kings of Tanjavur where too he was greatly honoured.
Appaya Dikshita wrote almost hundred and four works. He followed the philosophy of Srikantha. According to an inscription found in a Siva temple at his birthplace, Adayapalam, it is said that he taught a Sanskrit philosophical work named 'Srikantha Bhashya' to five hundred students. Chinna Bommu Nayaka provided land and gold to these students to help them to continue with their studies on the request of Appaya. The active involvement of him in debates with scholars of other systems of philosophy kept him often busies.
Apart from being a good poet and scholar, Appaya Dikshita was a great Siddha-yogi. It is said that whenever he used to sit for meditation or for worship of the Almighty, he used to keep a bundle of his towel in front of him. Then he transferred all the evils and troubles within him to these towels through his yogic powers. All the students of him watched in surprisingly the towels jumping around the place. Later he explained them how he transferred his ailment which was in the form of an evil spirit to the cloth and then took it back soon after his meditation was over. These experiences were really very thrilling.
There is one more story about his mystic devotion. This one is related to his work named 'Atmarpana-stuti', which is a small work of fifty stanzas. It is believed that through this poem he makes the inner self-melt as it were by his wonderful mystic poetry. The true devotion to the Supreme Power can be seen in it. The inner mental state of a great devotee is reflected in it, where the ego vanishes fully. There is a very interesting story behind the composition of this work. Once, he wanted to test his own devotion to the Lord and so he consumed the 'Datura' juice, which results intoxication. Then, he asked his disciples to write down whatever he utters during the stage when his consciousness was disturbed. Generally, in such a stage the suppressed and hidden thoughts get released from one. And when the students completed writing what he said, it came out as the 'Atmarpana-stuti', which is therefore also called 'Unmatta-panchasati'
