Dehadhyasa — The Identification with the Body
Dehadhyasa (identification with the body) is the primary expression of Avidya — the mistaken belief that 'I am this body' which generates all the suffering of mortality, limitation, and vulnerability.
Dehadhyasa (Deha = body, Adhyasa = superimposition/identification) is the most immediate and pervasive form of Avidya — the sense 'I am this body.' Because the Atman is experienced through the body and seems to be located in it, the mind concludes 'I am the body.' This identification generates all the characteristic anxieties of ordinary life: fear of physical harm, disease, and death; the drive for physical pleasure and the aversion to physical pain; the sense of being physically bounded and separate from others; and ultimately the existential terror of one's own mortality. Shankara's Vivekachudamani devotes many verses to dismantling Dehadhyasa: the Atman cannot be the body because the body is an object known to the Atman; the body is born, grows, and dies — the Atman is unborn and deathless; the body has spatial location — the Atman is omnipresent. The recognition that 'I am not this body but the Atman that witnesses this body' is one of the first fruits of consistent Vedantic inquiry.
I am not the body. I have a body. The body is an object; I am the subject. The body is seen; I am the seer.
Terror Management Theory (Greenberg, Solomon, Pyszczynski) documents the pervasive influence of mortality salience — awareness of one's own bodily death — on all human behavior, confirming the Advaita insight that Dehadhyasa (body identification) is the root driver of much of the anxiety, defensiveness, and striving of ordinary human life.

- What Advaita Vedanta says about the self
The first error named is the sense that I am this body. The reply is almost grammatical: the body is seen, and you are the one seeing it.
- What Advaita Vedanta says about illness and the body failing
The sentence "I am this body" is, for Advaita, the most pervasive of all errors, and illness is where it presents the bill. Shankara's counter-argument is structural: the body is an object known to you, it is born and dies, it occupies one location — none of which holds for the knower.
