If we chant this vibration of transcendental sound with devotion and with attention, that is the highest type of meditation and yoga. And very easy. The process is that you chant Hare Kṛṣṇa, and exactly the same sound you hear. So your mind is concentrated on this Kṛṣṇa, and Kṛṣṇa is not different. This sound Kṛṣṇa is not different from person Kṛṣṇa. Therefore when we chant Hare Kṛṣṇa, Hare Kṛṣṇa, Kṛṣṇa Kṛṣṇa, Hare Hare / Hare Rāma, Hare Rāma, Rāma Rāma, Hare Hare, it is as good as Kṛṣṇa.
Therefore it is stated here that "My appearance, disappearance and activity and glories, they are divyam." Divyam means transcendental. They do not belong to this world of duality. This world is of duality. But transcendental means that it is above, above this dualism. It is the absolute world. So anyone who understands this fact, that Kṛṣṇa is not different from this sound Kṛṣṇa, Kṛṣṇa is not different from this Bhagavad-gītā, Kṛṣṇa is not different from the . . . from anything which is connected with Kṛṣṇa . . . these things have to be understood.
