Our misunderstanding is due to dirty things within our hearts. So first benefit of chanting Hare Kṛṣṇa mahā-mantra will be that all the dirty things within your heart will be cleansed. Ceto-darpaṇa-mārjanaṁ bhava-mahā-dāvāgni-nirvāpanaṁ. And immediately you'll be relieved from the blazing fire of this material existence. This material existence is compared with a blazing forest fire. Forest fire means . . . nobody goes to set fire in the forest, but it takes places automatically. Similarly, in this material world, however peacefully you want to live, without God consciousness you cannot live peacefully. It is not possible. Forget it.
Therefore, if you think of Kṛṣṇa, or God, always, immediately you'll be freed from the conflagration of the blazing fire of this material . . . ceto-darpaṇa-mārjanaṁ bhava-mahā-dāvāgni-nirvāpanaṁ. And as soon as this blazing fire of material existence is extinguished, immediately you come to the platform of blissfulness. Ceto-darpaṇa-mārjanaṁ bhava-mahā-dāvāgni-nirvāpanaṁ śreyaḥ-kairava-candrikā (CC Antya 20.12). Then that blissfulness will increase one after another, one after another. Just like the comparison has been given just like the moon.
