Lord Visnu 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 Visnu. It is said in the Brahma-samhita 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 Syamasundara is so kind to His devotee.
