If you believe Kṛṣṇa, then the result will be that you can understand God, how He is working, how His energies are acting, how He is manifested, what is this material world, what is the spiritual world, what are these living creatures, what is their relationship—so many things in God's creation.
The whole Vedic literature are dealing in three things. First thing is that what is your relationship with God. Then the next step is that as soon as we understand our relationship with God, then we can act in that way. Just like a man and woman: they are not known to each other, but as soon as the relationship is established that one is husband and the other is wife, then the reciprocal dealing begins.
So unless you understand what is your relationship with God . . . generally, people believe that God is the father. Therefore son's business is to ask from father whatever we need. But that is very minor relationship. If you understand God perfectly well . . . and there is very intricate relationship also. That relationship will be revealed when you are perfectly liberated.
Each and every living creature has got a particular relationship with God. We have forgotten that. So when that relationship will be revealed in the process of devotional activities, Kṛṣṇa consciousness, you should know that is the perfection of your life. That is the perfection of our life.
So Kṛṣṇa consciousness is a great science. It is not a sentiment or mental speculation or bluff. It is based on scientific proposition, as described in the Bhagavad-gītā, as described in the Vedas, as described in the Saṁhitās, as accepted by the authorities like Lord Caitanya, Rāmānujācārya, Madhvācārya, Nārada, Asita, Vyāsa. There are so many authorities. So Kṛṣṇa consciousness is not an ordinary, bluff-making or a money-making business. It is something reality. And if you take to it seriously, your life will be successful.
