Thayumanavar's idea of Samarasam was his solution to this conflict based on doctrinal differences on the nature of ultimate reality. It was not merely an intellectual exercise, but the expression of a deep and comprehensive experience and realization of the truth that the facets of ultimate reality exclusively emphasized by Advaita Vedanta and Shaiva Siddhanta are complementary facets of one reality.
Tayumanavar says: "Always, my deeds are Your deeds. I am non-different from you, as my being as "I" cannot be apart or without you. The nature (svabhdva) of Vedanta Siddhdnta Samarasa is just this."
It is the final leap at the culmination of spiritual endeavour and total renunciation. The total and complete surrender.
