dhiyā viśuddhayā dadhyau
tathā prādurabhūd dhariḥ
Lord Viṣṇu is all-pervading. Any devotee who, in sanctified meditation, following the regulative principles, chants the required mantras in service and in a devotional mood can see Viṣṇu. It is said in the Brahma-saṁhitā that a devotee whose eyes are anointed with the ointment of love of Godhead can see the Supreme Personality of Godhead always within his heart. Lord Śyāmasundara is so kind to His devotee.
