A fully Krsna conscious person, although situated in this material world, does not see anything but Krsna, anywhere and everywhere. This is the sign of a maha-bhagavata. The maha-bhagavata sees Krsna everywhere because of his attitude of pure love for Krsna. As confirmed in the Brahma-samhita (5.38):

I worship the primeval Lord, Govinda, who is always seen by the devotee whose eyes are anointed with the pulp of love. He is seen in His eternal form of Syamasundara, situated within the heart of the devotee. An exalted devotee, or mahatma, who is rarely to be seen, remains fully conscious of Krsna and constantly sees the Lord within the core of his heart. It is sometimes said that when one is influenced by evil stars like Saturn, Rahu or Ketu, he cannot make advancement in any prospective activity. In just the opposite way, Prahlada Maharaja was influenced by Krsna, the supreme planet, and thus he could not think of the material world and live without Krsna consciousness. That is the sign of a maha-bhagavata. Even if one is an enemy of Krsna, a maha-bhagavata sees him to be also engaged in Krsnas service. Another crude example is that everything appears yellow to the jaundiced eye. Similarly, to a maha-bhagavata, everyone but himself appears to be engaged in Krsnas service.
