Transliteration / Meaning
ye tvetad abhyasūyanto nānutiṣhṭhanti me matam
sarva-jñāna-vimūḍhāns tān viddhi naṣhṭān achetasaḥ
Translation
But those who, out of envy, disregard these teachings and do not follow them are to be considered bereft of all knowledge, befooled, and ruined in their endeavors for perfection.
Purport by Srila Prabhupada
The flaw of not being Krishna conscious is clearly stated herein. As there is punishment for disobedience to the order of the supreme executive head, so there is certainly punishment for disobedience to the order of the Supreme Personality of Godhead. A disobedient person, however great he may be, is ignorant of his own self, and of the Supreme Brahman, Paramatma and the Personality of Godhead, due to a vacant heart. Therefore there is no hope of perfection of life for him.
