[devotees repeat] Śrīmad-Bhāgavatam, Third Canto, Twenty-eighth Chapter, text number eighteen. [leads chanting of verse, etc.] kīrtanya-tīrtha-yaśasaṁ puṇya-śloka-yaśaskaram dhyāyed devaṁ samagrāṅgaṁ yāvan na cyavate manaḥ [SB 3.28.18] [02:46] Translation: "The glory of the Lord is always worth singing, for His glories enhance the glories of His devotees. One should therefore meditate upon the Supreme Personality of Godhead and upon His devotees. One should meditate on the eternal form of the Lord until the mind becomes fixed." Prabhupāda: kīrtanya-tīrtha-yaśasaṁ puṇya-śloka-yaśaskaram dhyāyed devaṁ samagrāṅgaṁ yāvan na cyavate manaḥ [SB 3.28.18] This is called meditation.
Yāvan, so long the mind is disturbed and deviates from our subject of meditation, one should practice this kīrtana. Kīrtanīyaḥ sadā hariḥ [Cc. Ādi 17.31]. Caitanya Mahāprabhu advises that the devotee should chant always, twenty-four hours, kīrtanya: "It is worth singing." It is worth singing, why? Puṇya ślokasya.
Puṇya ślokasya... Puṇya śloka yaśaskaram. Even if you do not fix up your mind—kīrtana means fix up your mind—but even if you do not fix up your mind, then you are still gainer. The more you glorify the Lord, you become pious simply by kīrtana.
It is not necessary that you understand, but if you go on chanting Hare Kṛṣṇa mahā-mantra, then you become pious. Puṇya-śloka. Kṛṣṇa's another name is Puṇya-śloka, Uttama-śloka. Simply by chanting "Kṛṣṇa," you become pious. So dhyāyed devaṁ samagrāṅgam.
The dhyāna, the meditation, should begin from the lotus feet. As soon as you begin kīrtana, first of all concentrate your mind on the lotus feet, not all of a sudden jump over the face. Be practiced to think over the lotus feet, then still higher, the knees, then the thighs, then the belly, then the chest. In this way, at last go to the face.
This is the process. It is described in the Second Canto. The process is how to think of Kṛṣṇa., man-manā bhava mad-bhaktaḥ [Bg. 18.65]. This is meditation.
