Srila Prabhupada: “… In other words, as the universal elements are both within and without, similarly the Lord’s name, form, quality, pastimes, entourage, etc., as they are described in the revealed scriptures or as performed in the Vaikuṇṭhalokas, far, far beyond the material cosmic manifestation, are factually being televised in the heart of the devotee. The man with a poor fund of knowledge cannot understand, although by material science one can see things far away by means of television. Factually, the spiritually developed person is able to have the television of the kingdom of God always reflected within his heart. That is the mystery of knowledge of the Personality of Godhead…” Link to this page: https://prabhupadabooks.com/sb/2/9/35
