पुरुषत्वेन वै स्थाणुर्जलत्वेन मरीचिका ।विनिर्णीता विमूढेन देहत्वेन तथाऽऽत्मता ॥ ७३ ॥
In plain words
A tree stump gets mistaken for a man in the dark. A mirage gets mistaken for water. In just the same way, someone confused mistakes the Self for the body.
Close to the Sanskrit
Indeed, a stump is mistaken as a man, a mirage as water; likewise, selfhood is mistaken as body-hood by the deluded one.
