So this human form of body is given to us by nature to understand God. In other forms of life there is no chance of understanding God. Therefore it is our duty, everyone's duty, before the next death comes, we must understand what is God. If we simply misuse this body like cats and dogs, then we are missing the chance. We cannot say that we are free. That is not possible. We are completely under the control of the material nature. That is stated in the Bhagavad-gītā:
- prakṛteḥ kriyamāṇāni
- guṇair karmāṇi sarvaśaḥ
- ahaṅkāra-vimūḍhātmā
- iti manyate mūḍha
- (BG 3.27)
That we, everyone of us, at the present moment in our conditional state of life, we are completely under the, I mean to say, mercy or care of the material nature. There are three modes of material nature, namely goodness, passion and ignorance. When we are under the control of this material nature, we associate with either of these qualities. If we associate with the quality of goodness, then we are promoted in the higher world. This is stated in the Bhagavad-gītā:
- ūrdhvaṁ gacchanti sattva-sthā
- madhye tiṣṭhanti rājasāḥ
- jaghanya-guṇa-vṛtti-sthā
- adho gacchanti tāmasāḥ
- (BG 14.18)
Means "Those who are associating with the modes of material nature goodness, they will be promoted to the higher planetary system. Those who are associating with the modes of passion, they'll remain in the middle planetary system." (break)
So as it is said that in the beginning was the word, that means before the creation there was the transcendental sound. So that word, or transcendental sound, is not like the material sound. If we associate with the transcendental sound Hare Kṛṣṇa, then we become purified to become transcendental. Just like we can have a crude example. You take one iron rod and put into the fire. The iron rod will be warm, warmer, and gradually it will be red hot. When it is red hot, then it is no longer the iron rod; it is fire. So how it has become fire? By association with the fire. Simply, therefore, if you simply keep yourself touch with God by the vibration of transcendental sound, gradually you become godly. So as soon as you become godly, you become the same quality-aiśvaryasya samagrasya: full riches, full power, full strength, full knowledge, everything full. Therefore the Vedic instruction is tamasi mā jyotir gamaḥ: "Don't keep yourself in darkness. Come to the light." So our only request is at the present moment, the whole world is for want of godly understanding. They are in darkness. So our duty is, when we have got this privilege of this human form of life, we should not keep ourself in darkness. Darkness means without any knowledge of the soul and God. So long I am thinking that "I am this body," it is in darkness. Except the human being, any other living being, they are all in darkness. Therefore human being's business is not to keep himself in darkness, but come to the light. So long we have got this material body, there are four necessities of life. They are eating, sleeping, sex intercourse and defense. So the cats and dogs, they also eat, they sleep, they have sex life and they can defend also. So therefore a human being should not be educated only for these four principles of animal necessities. The human necessity is to understand God. Therefore in civilized human society, there is some system of religion. Either you call it Christianity, Muhammadanism, or Hinduism, in civilized society there must be some form of religion. And a human being is supposed to follow the principles to have complete knowledge about God and himself, to know "What is the relationship between God and me?" and what is the goal of life.
So it doesn't matter whether you are Christian, Hindu, Muslim. The real purpose of life is to know God. And in the Vedic literature it is said, dharmaṁ tu sākṣāt bhagavat-praṇītam: Dharma, or religion, means the codes given by God.
