When our eyes are anointed with love of God, we can see Him everywhere. That is the injunction of the sastras. We have to develop our seeing power by developing love of Godhead. Premanjana-cchurita bhakti-vilocanena [Bs 5.38].
When one is sufficiently developed in Krsna consciousness, he can see the Lord every moment within his heart and everywhere, wherever he goes.
Srila Prabhupada, Lecture, 27 June 1971
