The senses, the mind, and the thought are said to be his (lust or desire) abode; by means of these, obstructing knowledge, he deludes the dweller in the body.
Senses are the strong hold of desire; desire brings them in contact with the objects, bewilders the mind & thought and prevents the acquisition of true knowledge; or if acquired, renders it inefficient for the higher purpose.
