Because of self view, many past religious seekers believed that “true self,” “universal self,” “ultimate self ” is the ultimate happiness. Therefore, they searched for that “ultimate happiness,” and they call it “Ātman.”
Clinging to that self view, we also believe that atta is “self”; therefore, anatta must be no-self or not-self, and we believe that the Buddha teaches us the doctrine of no-self or not-self.
Clinging to self view, we affirm that there is no self to experience, or we cannot experience self, or the self can be experienced without any means, or there is no self in the first place, self is the grasping, self is real, self is unreal, self is observable, self is not observable, self is permanent, self is impermanent, there is no self because there is no true essence, there is one’s own true essence, there isn’t anybody who is aware, there is an awareness that aware the impermanence… We develop countless theories to explain the existence or non-existence of the “self” by explicitly or implicitly referring to it.
However, the Buddha cautions us that we should not cling to any doctrine of self (true self, fake self, no self, not self, minimal self, multifaceted self, subjective self, objective self, intersubjective self, self beyond the All, unknowable self, indescribable self, ultimate self…). He calls that clinging as “self view,” a thicket of views, and that is the first fetter that needs to be abandoned.
If the Buddha told us that we should not cling to any doctrine of self, then why did he teach us the doctrine of no-self or not-self? If the Buddha has abandoned all doctrines of self, how can he do so?
If we drop the self view, then atta is no longer an “ultimate self” or "Self” or anything related to “self.” It simply is the ultimate happiness, the final goal that a religious seeker is looking for. Therefore, anatta is simply the doctrine of what is not the ultimate happiness, or anatta is the doctrine of the end of all sufferings. It has nothing to do with “self” . This doctrine is the tool to find that ultimate happiness, and this “atta” can be found, and the Buddha called it “Tathagatha.”
The “Tathagatha” has nothing to do with “self” does not mean that the Tathagatha is no-self/not-self. Moreover, we also cannot say that because it is not no-self/not-self then it must be a self . In fact, the Tathagatha is indescribable and unidentifiable. Any attempt to describe or identify it is incorrect. The Buddha told us that the Tathagatha is beyond logic and unfathomable.
In quantum physics, scientists talk about superposition. They understand that there is “superposition”, but they cannot describe or observe it. It is against normal logic.
We can only know about the Tathagatha by direct experience, not by logic, observation or speculation. This is what jhana is for. Jhana is the practice for direct experience. If we do not have direct experience, or at least a glimpse of it, then we do not know what jhana is.
Religious seekers in the past were looking for the ultimate self to find the ultimate happiness. They called that “atman”. They believe the ultimate self is the ultimate happiness. The Buddha told them that if they want to find that ultimate happiness, if they want to reach that goal, they should drop that “self view, ” then they can find that “atman.” To distinguish this new “atman” from the old “atman,” he called it “Tathagatha.” However, this is just for communication purposes since the Tathagatha is indescribable, and unidentifiable. Therefore, any attempt to identify it is incorrect.
Because of self view, we think that there is “self,” there is “I”, there is no self, there is no “I”, how can I experience self? How can I experience no-self? Only perception, feeling,… arises and ceases, but there is no self or person that feels or perceives. Or I can feel the pain; therefore, there is self…We have argued this for thousands of years, and will be more. If we do not drop this self view then we will never be able to realize the final goal or reach the end of all sufferings.
If we tell others that atman is a self or not a self, exist or not exist, then they will argue until the end of the world.
