So it is the duty of every human being to understand his constitutional position, his relation with God and, understanding the relation, to act accordingly, and then our life becomes successful. This human form of life is meant for that purpose. We are missing the point. So long we are living, sometimes we challenge that, "There is no God," "I am God," or somebody says: "I don't care for God." But actually this challenge will not save us. God is there. We can see God in every moment. But if we deny to see God, then God will be present before us as the cruel death.
There are different features of the Supreme Personality of Godhead, because He is the original root cause of all cosmic manifestation. In the Bhagavad-gītā there is nice description how you can gradually understand and see God personally, face to face. Just like the Personality of Godhead says therein that, "I am the taste in water. I am the sunlight. I am the moonlight. I am the sound vibration in the sky and I am the supreme character of a great personality."
So if we (are) actually serious to understand the science of God, if we try to follow the injunction given in the Bhagavad-gītā . . . just like God is the taste of the water. Everyone is tasting water daily, not only once, but several times. So if we remember this instruction of Bhagavad-gītā, that the taste of the water is God, then the God realization begins, becomes . . . begins.
Similarly, it is said there that God is the light of the moon, God is the light of the sun. Every one of us has seen the sunlight and the moonshine, so how we can say that we have not seen God? Similarly, Kṛṣṇa says that, "I am the sound vibration in the sky." So who has not heard the sound vibration of the cloud in the sky? So as soon as we hear the sound vibration in the sky, we can see God or we can hear God. At last, Kṛṣṇa says in the Bhagavad-gītā that mṛtyuḥ sarva-haraś cāham (BG 10.34). If one does not see God, then, Kṛṣṇa says: "I am the death, cruel death, who takes away everything from everyone."
The conclusion is that everyone sees God at every moment, but the atheist class, they do not accept that he is seeing God. He is denying or telling lies that he is not seeing God. But a devotee of God, he sees God at every moment within his heart. So the difference of seeing God by a devotee and difference of . . . and denying, denial by the nondevotee, is this, that the atheist class or the atheist can see God at his last stage as death, whereas the devotee sees God by his devotional service every moment and every step of his life.
So this human form of life is especially . . . it is given by nature to realize God. If we don't utilize this human form of life to understand ourselves and God and our relationship, then we are committing a suicidal policy. Our this Kṛṣṇa consciousness movement is just an attempt to educate the foolish human civilization without any sense of God. Our life . . . as we are spirit soul, we are evolving through many species of life, and if we don't take advantage of this human form of life, then we are missing the chance.
