The mind is naturally restless, going hither and thither, but it can rest in the sound vibration of Kṛṣṇa. One must thus meditate on paramaṁ puruṣam, the Supreme Personality of Godhead in the spiritual kingdom, the spiritual sky, and thus attain Him. The ways and the means for ultimate realization, ultimate attainment, are stated in the Bhagavad-gītā, and the doors of this knowledge are open for everyone. No one is barred out. All classes of men can approach Lord Kṛṣṇa by thinking of Him, for hearing and thinking of Him is possible for everyone.
The Lord further says (Bg. 9.32-33):
- māṁ hi pārtha vyapāśritya
- ye 'pi syuḥ pāpa-yonayaḥ
- striyo vaiśyās tathā śūdrās
- te 'pi yānti parāṁ gatim
- kiṁ punar brāhmaṇāḥ puṇyā
- bhaktā rājarṣayas tathā
- anityam asukhaṁ lokam
- imaṁ prāpya bhajasva mām
Thus the Lord says that even a merchant, a fallen woman or a laborer or even human beings in the lowest status of life can attain the Supreme. One does not need highly developed intelligence.
