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.
PURPORT
One has to fix his mind on the Supreme Personality of Godhead constantly. When one is accustomed to thinking of one of the innumerable forms of the Lord— Kṛṣṇa ,  Viṣṇu ,  Rāma ,  Nārāyaṇa , etc.—he has reached the perfection of  yoga . This is confirmed in the  Brahma-saṁhitā : a person who has developed pure love for the Lord, and whose eyes are smeared with the ointment of transcendental loving exchange, always sees within his heart the Supreme Personality of Godhead. The devotees especially see the Lord in the beautiful blackish form of Śyāmasundara. That is the perfection of  yoga .

Om̄ tad viṣṇoḥ paramaṁ padaṁ sadā paśyanti sūrayaḥ : the form of  Viṣṇu  is the highest individuality and is always visible to sages and saintly persons.

There are eight kinds of forms recommended for the devotees to see. The forms may be made out of sand, clay, wood or stone, they may be contemplated within the mind, or made of jewel, metal or painted colors, but all the forms are of the same value. It is not that one who meditates on the form within the mind sees differently from one who worships the
