Prahlāda Mahārāja said: One who is sufficiently intelligent should use the human form of body from the very beginning of life — in other words, from the tender age of childhood — to practice the activities of devotional service, giving up all other engagements. The human body is most rarely achieved, and although temporary like other bodies, it is meaningful because in human life one can perform devotional service. Even a slight amount of sincere devotional service can give one complete perfection.
The whole purpose of Vedic civilization and of reading the Vedas is to attain the perfect stage of devotional service in the human form of life. According to the Vedic system, therefore, from the very beginning of life, the brahmacarya system is introduced so that from one’s very childhood — from the age of five years — one can practice modifying one’s human activities so as to engage perfectly in devotional service. As confirmed in Bhagavad-gītā (2.40), svalpam apy asya dharmasya trāyate mahato bhayāt: “Even a little advancement on this path can protect one from the most dangerous type of fear.” Modern civilization, not referring to the verdicts of Vedic literature, is so cruel to the members of human society that instead of teaching children to become brahmacārīs, it teaches mothers to kill their children even in the womb, on the plea of curbing the increase of population. And if by chance a child is saved, he is educated only for sense gratification. Gradually, throughout the entire world, human society is losing interest in the perfection of life. Indeed, men are living like cats and dogs, spoiling the duration of their human lives by actually preparing to transmigrate again to the degraded species among the 8,400,000 forms of life.
The Kṛṣṇa consciousness movement is anxious to serve human society by teaching people to perform devotional service, which can save a human being from being degraded again to animal life. As already stated by Prahlāda Mahārāja, bhāgavata-dharma consists of śravaṇaṁ kīrtanaṁ viṣṇoḥ smaraṇaṁ pāda-sevanam/ arcanaṁ vandanaṁ dāsyaṁ sakhyam ātma-nivedanam. In all the schools, colleges and universities, and at home, all children and youths should be taught to hear about the Supreme Personality of Godhead. In other words, they should be taught to hear the instructions of Bhagavad-gītā, to put them into practice in their lives, and thus to become strong in devotional service, free from fear of being degraded to animal life. Following bhāgavata-dharma has been made extremely easy in this Age of Kali. The śāstra says:
harer nāmaiva kevalam
kalau nāsty eva nāsty eva
nāsty eva gatir anyathā
One need only chant the Hare Kṛṣṇa mahā-mantra. Everyone engaged in the practice of chanting the Hare Kṛṣṇa mahā-mantra will be completely cleansed, from the core of his heart, and be saved from the cycle of birth and death.
The Lord says in Bhagavad-gītā (5.29):
sarva-loka-maheśvaram
suhṛdaṁ sarva-bhūtānāṁ
jñātvā māṁ śāntim ṛcchati
“The sage who knows Me as the ultimate purpose of all sacrifices and austerities, the Supreme Lord of all planets and demigods and the benefactor and well-wisher of all living entities attains peace from the pangs of material miseries.” Simply by understanding these three facts — that the Supreme Lord, Viṣṇu, is the proprietor of the entire creation, that He is the best well-wishing friend of all living entities, and that He is the supreme enjoyer of everything — one becomes peaceful and happy. For this transcendental happiness, the living entity has wandered throughout the universe in different forms of life and different planetary systems, but because he has forgotten his intimate relationship with Viṣṇu, he has merely suffered, life after life.
Therefore, the educational system in the human form of life should be so perfect that one will understand his intimate relationship with God or Viṣṇu. Every living entity has an intimate relationship with God. One should, therefore, glorify the Lord in the adoration of śānta-rasa or revive his eternal relationship with Viṣṇu as a servant in dāsya-rasa, a friend in sakhya-rasa, a parent in vātsalya-rasa or a conjugal lover in mādhurya-rasa. All these relationships are on the platform of love. Viṣṇu is the center of love for everyone, and therefore the duty of everyone is to engage in the loving service of the Lord. As stated by the Supreme Personality of Godhead (Bhāg. 3.25.38), yeṣām ahaṁ priya ātmā sutaś ca sakhā guruḥ suhṛdo daivam iṣṭam. In any form of life, we are related with Viṣṇu, who is the most beloved, the Supersoul, son, friend and guru. Our eternal relationship with God can be revived in the human form of life, and that should be the goal of education. Indeed, that is the perfection of life and the perfection of education.
In the material world, in any form of life, there is some so-called happiness and so-called distress. No one invites distress in order to suffer, but still, it comes. Similarly, even if we do not endeavor to obtain the advantages of material happiness, we shall obtain them automatically. This happiness and distress are obtainable in any form of life, without endeavor. Thus there is no need to waste time and energy fighting against distress or working very hard for happiness. Our only business in the human form of life should be to revive our relationship with the Supreme Personality of Godhead and thus become qualified to return home, back to Godhead. Material happiness and distress come as soon as we accept a material body, regardless of what form. We cannot avoid such happiness and distress under any circumstances. The best use of human life, therefore, lies in reviving our relationship with the Supreme Lord, Viṣṇu.
