activities artificially created by the modes of material nature and stop the flow of the intelligence in wakefulness, dreaming and deep sleep. In other words, when one takes to Kṛṣṇa consciousness, his ignorance is immediately dissipated.
PURPORT
This is confirmed in  Bhagavad-gītā  (14.26):
māṁ ca yo 'yabhicāreṇa bhakti-yogena sevate sa guṇān samatītyaitān brahma-bhūyāya kalpate
“One who engages in full devotional service, who does not fall down in any circumstance, at once transcends the modes of material nature and thus comes to the level of Brahman.” By the practice of  bhakti-yoga , one immediately comes to the spiritual platform, transcendental to the actions and reactions of the three modes of material nature. The root of ignorance is material consciousness, which must be killed by spiritual consciousness, or Kṛṣṇa consciousness. The word  bīja-nirharaṇam  refers to burning the root cause of material life to ashes. In the Medinī dictionary,  yoga  is explained by its result:  yoge 'pūrvārtha-samprāptau saṅgati-dhyāna-yuktiṣu . When one is put into an awkward position because of ignorance, the process by which one can be freed from this entanglement is called  yoga . This is also called liberation.  Muktir hitvānyathā-rūpaṁ svarūpeṇa vyavasthitiḥ .  Mukti  means giving up one’s position in ignorance or illusion, by which one thinks in a way contrary to his constitutional position. Returning to one’s constitutional position is called  mukti , and the process by which one does this is called  yoga . Thus  yoga  is above  karma ,  jñāna  and  sāṅkhya . Indeed,  yoga  is the ultimate goal of life. Kṛṣṇa therefore advised Arjuna to become a  yogī  ( tasmād yogī bhavārjuna ). Lord Kṛṣṇa further advised in  Bhagavad-gītā  that the first-class  yogī  is he who has come to the platform of devotional service.
