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-gītā, 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-gītā.
In conclusion, Bhagavad-gītā is a transcendental literature which one should read very carefully. Gītā-śāstram idaṁ puṇyaṁ yaḥ paṭhet prayataḥ pumān. If one properly follows the instructions of Bhagavad-gītā, one can be freed from all miseries and anxieties in this life, and one's next life will be spiritual. Viṣṇoḥ padam avāpnoti bhaya-śokādi-varjitaḥ. (Gītā-māhātmya 1)
