Of course, it is very difficult task to understand Kṛṣṇa, but it is due to our misunderstanding or uncleanliness of the consciousness. If the consciousness is cleansed, then you can very easily understand what is Kṛṣṇa. This cleaness of the consciousness can be effected by chanting the transcendental vibration Hare Kṛṣṇa, Hare Kṛṣṇa, Kṛṣṇa Kṛṣṇa, Hare Hare/ Hare Rāma, Hare Rāma, Rāma Rāma, Hare Hare. It is open to all. It is not a secret thing. We are chanting Hare Kṛṣṇa mantra very loudly. Everyone can hear it and chant it. If you regularly chant this Hare Kṛṣṇa mantra, then gradually your consciousness will be cleansed. The process of advancement in chanting Hare Kṛṣṇa mantra is said in the Vedic literature, ceto-darpaṇa-mārjanam (CC Antya 20.12). The first installment of benefit by chanting Hare Kṛṣṇa mantra is that your consciousness becomes cleansed. And as soon as your consciousness becomes cleansed, the tribulations or the miserable condition of material life becomes extinguished. The miserable condition of material life is compared with the blazing fire in the forest. As it is very difficult to extinguish the forest fire, similarly, the problems of material life cannot be extinguished simply by material benefits. As the blazing fire in the forest cannot be extinguished by the help of fire brigade or bucketful of water, similarly, by material adjustment, the problems of material miseries cannot be solved.
Because we are, by constitutional position, we are spirit soul, any material comforts will not give us actually a favorable condition of life. Just like a fish taken out of the water cannot be comforted by material comfort, er, by comfort in the land. Unless the fish is again thrown into the water, any kind of comforts on the land will not make him happy.
