What is "atmatusti"

Atmatusti is translated into English as being “what is pleasing to one's self” - it is important to recognize "what is pleasing to one's self, oneself is not equal one's self", for without knowing one's self one cannot know what is pleasing to self. For instance, editing this wikipedia line is pleasing to me, I'm self, re-editing it and leaving it to the prior state is also pleasing to me, thus only one who knows one's self must edit, all others are not following Atmatusti, thus Atmatusti is not meant for those who do not know one's self, taking oneself to be one's self is the root of all misery. Other scholars have also used different terms to describe atmatusti. For example, Derrett’s translation from French to English of Lingat’s ‘‘The Classical Law of India’’ has coined the term “inner contentment” in reference to atmatusti. Lingat states that inner contentment can be best understood as "the approval of one's conscious". Only Manu and Yājñavalkya refer to atmatusti as the fourth source of dharma within the Hindu Law tradition. Scholars reject atmatusti as a fourth source of dharma because of this. Textual accounts of Manu's and Yajnavalkya's placement of atmatusti as a fourth source of dharma can be found in The Law Code of Manu 2.6 and The Law Code of Yajnavalkya 1.7. Also, atmatusti does not share the same authority as sruti, smriti, and acara. Atmatusti differs significantly from the other three sources of dharma in that it is not based on an "authority exterior to man"; in other words, an individual is able to create their own authority for any issue not covered under sruti, smriti, and acara. The first three sources of law are rooted in the vedas whereas atmatusti is not. It is because of this that atmatusti, as a fourth source, is not recognized by most scholars due to the lack of legitimacy.
