The mind is always flying to this and that, but one must practice concentrating the mind always on the form of the Supreme Lord, Sri Krsna, or on the sound of His name. The mind is naturally restless, going hither and thither, but it can rest in the sound vibration of Krsna. One must thus meditate on paramam purusam, 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-gita, and the doors of this knowledge are open for everyone. No one is barred out. All classes of men can approach Lord Krsna by thinking of Him, for hearing and thinking of Him is possible for everyone.
The Lord further says (Bg. 9.32-33):
- mam hi partha vyapasritya
- ye 'pi syuh papa-yonayah
- striyo vaisyas tatha sudras
- te 'pi yanti param gatim
- kim punar brahmanah punya
- bhakta rajarsayas tatha
- anityam asukham lokam
- imam prapya bhajasva mam
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. The point is that anyone who accepts the principle of bhakti-yoga and accepts the Supreme Lord as the summum bonum of life, as the highest target, the ultimate goal, can approach the Lord in the spiritual sky. If one adopts the principles enunciated in Bhagavad-gita, he can make his life perfect and make a permanent solution to all the problems of life. This is the sum and substance of the entire Bhagavad-gita.
