Those who are yogis, bhakta-yogis, because they are in love with God, Kṛṣṇa, they are seeing every moment within their heart the Supreme Personality of Godhead. Anyone you love, you see always within your heart. Similarly, if you have love for God, Kṛṣṇa, then you can see Kṛṣṇa always. That is called yoga system.
