BG Chap 18 - Result of one who studies and hears the Gītā

One who studies the conversation between Kṛṣṇa and Arjuna would have worshipped the Lord thru the sacrifice of knowledge, which is superior to the sacrifice of materials. Such a person worships the Lord with his intelligence.

One who hears this teaching with faith and without envy would become free of sin and attain the planets of those who perform aśvamedha sacrifices, or the auspicious world of the devotees such as Dhruvaloka, or the various Vaikuṇṭha planets. Although not everyone is a devotee, still there are many men who are not envious of Kṛṣṇa. They have faith in Him as the Supreme Personality of Godhead. If such persons hear from a bona fide devotee about the Lord, the result is that they become at once free from all sinful reactions and after that attain to the planetary system where all righteous persons are situated. Therefore simply by hearing Bhagavad-Gītā, even a person who does not try to be a pure devotee attains the result of righteous activities. Thus a pure devotee of the Lord gives everyone a chance to become free from all sinful reactions and to become a devotee of the Lord.
