We work not with our body, actually, but with our mind and intelligence. So if the intelligence and the mind are always engaged in the thought of the Supreme Lord, then naturally the senses are also engaged in His service. Superficially, at least, the activities of the senses remain the same, but the consciousness is changed. The Bhagavad-gītā teaches one how to absorb the mind and intelligence in the thought of the Lord. Such absorption will enable one to transfer himself to the kingdom of the Lord. If the mind is engaged in Kṛṣṇa's service, then the senses are automatically engaged in His service. This is the art, and this is also the secret of Bhagavad-gītā: total absorption in the thought of Śrī Kṛṣṇa.
Modern man has struggled very hard to reach the moon, but he has not tried very hard to elevate himself spiritually. If one has fifty years of life ahead of him, he should engage that brief time in cultivating this practice of remembering the Supreme Personality of Godhead. This practice is the devotional process:
- śravaṇaṁ kīrtanaṁ viṣṇoḥ
- smaraṇaṁ pāda-sevanam
- arcanaṁ vandanaṁ dāsyaṁ
- sakhyam ātma-nivedanam
- (SB 7.5.23)
These nine processes, of which the easiest is śravaṇam, hearing the Bhagavad-gītā from the realized person, will turn one to the thought of the Supreme Being. This will lead to remembering the Supreme Lord and will enable one, upon leaving the body, to attain a spiritual body which is just fit for association with the Supreme Lord.
