dehÄ« - the embodied soul; ajñaḥ - without perfect knowledge; ajita-á¹£aá¹-vargaḥ - who has not controlled the senses of perception and the mind; na icchan - without desiring; karmÄṇi - activities for material benefit; kÄryate - is caused to perform; koÅ›akÄraḥ - the silkworm; iva - like; ÄtmÄnam - himself; karmaá¹‡Ä - by fruitive activities; ÄcchÄdya - covering; muhyati - becomes bewildered.
As already explained, the influence of the modes of nature is very strong. The living entity entangled in different types of fruitive activity is like a silkworm trapped in a cocoon. Getting free is very difficult unless he is helped by the Supreme Personality of Godhead.
