The Pleasure Trap: How the Nucleus Accumbens Generates Illusion.

How this brain structure offers a fascinating physical archetype of our innate tendency to mistake illusion (maya) for reality.

The nucleus accumbens is the reward center in our brain that releases dopamine in response to what we find gratifying. Although useful for survival, this system can easily confuse illusion and reality, being activated indiscriminately by real, simulated, or imagined events. Viewed through the lens of Vedanta philosophy, the nucleus accumbens offers a fascinating physical archetype of our innate tendency to experience illusion (maya) as reality. We are born with a nucleus accumbens ready to project a sense of gratification, reward, and identification onto any object or experience, regardless of its validity or reality - thus generating the illusion of the self as limited to the mind/body.

The ancient Vedanta wisdom states that ordinary phenomenal reality is illusory, veiled by ignorance (avidya) of our true eternal nature as pure Consciousness (Brahman). Our senses do not perceive objectively, but actively reconstruct the world based on needs, expectations, desires, emotions and personal inclinations. Even the sense of "I" is an illusion, based on what we are attached to or avoid.  But through shravana (listening/reading scriptures), manana (reflection), and nididhyasana (meditation on the Mahavakyas), we can transcend these innate illusions and realize our eternal true nature.  Then gratification comes not from chasing ephemeral pleasures but from immersing in the bliss of the Self. We realize we have always been that eternal reality, and the rewards of the phenomenal world lose their grip on us as we rest in the knowledge "I am all".

For Vedanta, our true Self (atman) transcends the changing states of waking, dreaming, and deep sleep. These states are not the Self but illusions (maya) stemming from ignorance (avidya) of ultimate reality. Ultimate reality is Brahman, the transcendent Self of all, identical to our Self. Brahman is pure consciousness, being, and bliss. The fourth state, turiya, transcends and permeates the three states. Turiya means "the fourth" but is not sequential. It is the background of all states, the pure awareness witnessing them. Turiya is unchanged by states' fluctuations and remains constant. Turiya is liberation (moksha), realizing we are Brahman and freed from rebirth. 

The changing person in states is not us; we are turiya, formless consciousness witnessing the mind. Brain structures like the nucleus accumbens are in the illusory non-Self domain. Only in Turiya do we grasp the illusion in each experience and the never-veiled reality.
