The mahā–bhāgavata, the advanced devotee, certainly sees everything mobile and immobile, but he does not exactly see their forms. Rather, everywhere he immediately sees manifest the form of the Supreme Lord.”
Due to his deep ecstatic love for Kṛṣṇa, the mahā–bhāgavata sees Kṛṣṇa everywhere and nothing else. This is confirmed in the Brahma–saṁhitā (5.38): premāñjana-cchurita-bhakti-vilocanena santaḥ sadaiva hṛdayeṣu vilokayanti.
As soon as a devotee sees something-be it movable or inert-he immediately remembers Kṛṣṇa. An advanced devotee is advanced in knowledge. This knowledge is very natural to a devotee, for he has already read in the Bhagavad-gītā how to awaken Kṛṣṇa consciousness. According to Lord Kṛṣṇa in the Bhagavad-gītā (7.8):
Thus when a devotee drinks water or any other liquid, he immediately remembers Kṛṣṇa. For a devotee there is no difficulty in awakening Kṛṣṇa consciousness twenty-four hours a day. Caitanya Mahāprabhu therefore says here:
A saintly person, an advanced devotee, sees Kṛṣṇa twenty-four hours a day and nothing else. As far as movable and inert things are concerned, a devotee sees them all as transformations of Kṛṣṇa’s energy. As Lord Kṛṣṇa states in the Bhagavad-gītā (7.4):
“Earth, water, fire, air, ether, mind, intelligence and false ego-all together these eight constitute My separated material energies.” Actually nothing is separate from Kṛṣṇa. When a devotee sees a tree, he knows that the tree is a combination of two energies-material and spiritual. The inferior energy, which is material, forms the body of the tree; however, within the tree is the living entity, the spiritual spark, which is part and parcel of Kṛṣṇa. This is the superior energy of Kṛṣṇa within this world. Whatever living thing we see is simply a combination of these two energies. When an advanced devotee thinks of these energies, he immediately understands that they are manifestations of the Supreme Lord. As soon as we see the sun rise in the morning, we arise and set about doing our morning duties. Similarly, as soon as a devotee sees the energy of the Lord, he immediately remembers Lord Śrī Kṛṣṇa. A devotee who has purified his existence through devotional service sees only Kṛṣṇa in every step of life.
