Doubts of duality due to misidentification with body

Doubts of duality begin from the misconception of the material body, which is accepted as the self by less intelligent persons. The most foolish part of our ignorance is our identifying this material body with the self. Everything in relation with the body is ignorantly accepted as our own. Doubts due to misconceptions of "myself" and "mine" — in other words, "my body," "my relatives," "my property," "my wife," "my children," "my wealth," "my country," "my community," and hundreds and thousands of similar illusory contemplations — cause bewilderment for the conditioned soul.
