If you capture the association of Kṛṣṇa consciousness, you get sunshine, that Kṛṣṇa’s shining. This is the process of Kṛṣṇa consciousness. But unfortunately there are some people, they do not want it, or they have no knowledge. But this process is like that. We cannot be happy within this cloud-covered material existence. We are spirit by nature. We are sparks, spiritual sparks. We have to associate with Kṛṣṇa; then we can have our full-fledged.
Another example: just like there is fire, and there are small particles of sparks coming out of the fire. The sparks which is coming out of the fire, it falls down beyond the range of the flame, it becomes charcoal, carbon, immediately—black charcoal. But if it remains with the fire, it is as bright as the fire. All this a small spark.
Similarly, if you remain always in Kṛṣṇa consciousness fire, you are also as good as Kṛṣṇa, ānanda-cinmaya-rasa. And as soon as you go out of the boundary, or somehow or other you are covered, just like cloud, then you become black, or extinguished—no more fire, although the fire potency is there. Just like coal: the coal, it looks very blacks, carbon; but put it in the fire, it becomes red, very good fire.
Similarly, we are now out of the orbit, or the shining influence, of Kṛṣṇa, or the Supreme Personality of Godhead. We have to put ourselves again into that atmosphere of Kṛṣṇa; then we get full-fledged happiness, knowledge and eternal life. That is the process of Kṛṣṇa consciousness.
So Prahlāda Mahārāja says that to attain this Kṛṣṇa consciousness is not very difficult task. Actually it is so, it is not very difficult task. Simply we have to make association, and that association is very easily made, simply by chanting.
This process we are spreading, Hare Kṛṣṇa movement. If you simply chant Hare Kṛṣṇa, Hare Kṛṣṇa, Kṛṣṇa Kṛṣṇa, Hare Hare/ Hare Rāma, Hare Rāma, Rāma Rāma, Hare Hare, you will gradually realize ceto-darpaṇa-mārjanam (CC Antya 20.12).
