Thatātā is called so because a soul who attains it holds the same state forever. Once a soul achieves complete annihilation of karmans, he would never bind his soul with karmans again. Such stagnant state of a soul is nothing but tathātā.
The word sadāśiva is commonly used by Shaivates. Parabrahma is in vogue among Vedāntins.The word siddhātma popular in Jains and thatātā with Buddhists (one section of Buddhism).
All these words including nirvāṇa convey the meaning of total freedom of a soul from the bondage of karmans. It is the state of ultimate bliss where all causes of miseries are destroyed completely. A soul, who attains this state, does not have to go through pain of birth as well as death. Due to complete annihilation of karmans, in this state, a soul is no more affected by vices viz. attachment, aversion and delusion. Therefore, this state is known as the best.
