Cognitive Psychology deals with thinking.

In particular, cognitive psychology deals with thinking disorders which can cause an individual to experience mental problems.

One of the earliest cognitive psychologies was pure Buddhism, circa 600 B.C., created by the Buddha [The Enlightened One, or He Who Is Awake]—Siddartha Guatama of the Sakya.

The Essence of Buddhism: The Four Noble Truths]
1. Dukkha: Man suffers.
2. Tanha: Man suffers because of greed, defined as excessive desire.
3. Nirvana: Man’s suffering can be alleviated.
4. Marga: Man’s suffering can be alleviated by means of The Eightfold Path.
   1. Right View or Knowledge.

   3. Right Speech.
   4. Right Conduct.
   5. Right Livelihood
   6. Right Effort.
   7. Right Mind Control.

PURE Buddhism is the above essence without the following Eastern religious metaphysics:

A. Samsara: The Wheel of Birth and Rebirth, typically translated by Westerners as reincarnation.
B. Karma: The works done in a previous life have influence on one's station in a reincarnation.
C. Nirvana: Release from Samsara.

PURE Buddhism is cognitive psychology, and cognitive psychology works for many forms of mental disorders based upon errors of thought/thinking.

PURE Buddhism is not a religion; it is a psychology.
