CC Madhya 13.155
sei prema — parama prabala
lukāñā āmā āne, saṅga karāya tomā-sane,
prakaṭeha ānibe satvara
Kṛṣṇa has two kinds of presence — prakaṭa and aprakaṭa, manifest and unmanifest. These are identical for the sincere devotee. Even if Kṛṣṇa is not physically present, the devotee’s constant absorption in the affairs of Kṛṣṇa makes Him always present. This is confirmed in the Brahma-saṁhitā (5.38):
santaḥ sadaiva hṛdayeṣu vilokayanti
yaṁ śyāmasundaram acintya-guṇa-svarūpaṁ
govindam ādi-puruṣaṁ tam ahaṁ bhajāmi
Due to his intense love, the pure devotee always sees Lord Kṛṣṇa present within his heart. All glories to Govinda, the primeval Personality of Godhead! When Kṛṣṇa is not manifest before the inhabitants of Vṛndāvana, they are always absorbed in thoughts of Him. Therefore even though at that time Kṛṣṇa was living in Dvārakā, He was simultaneously present before all the inhabitants of Vṛndāvana. This was His aprakaṭa presence. Devotees who are always absorbed in thoughts of Kṛṣṇa will soon see Kṛṣṇa face to face without a doubt. In other words, devotees who are always engaged in Kṛṣṇa consciousness and are fully absorbed in thoughts of Kṛṣṇa certainly return home, back to Godhead. They then see Kṛṣṇa directly, face to face, talk with Him and enjoy His company. This is confirmed in the Bhagavad-gītā (4.9): tyaktvā dehaṁ punar janma naiti mām eti so ’rjuna.
Because during his lifetime a pure devotee is always speaking of Kṛṣṇa and engaging in His service, as soon as he gives up his body he immediately returns to Goloka Vṛndāvana, where Kṛṣṇa is personally present. He then meets Kṛṣṇa directly. This is successful human life. This is the meaning of prakaṭeha ānibe satvara: The pure devotee will soon see the personal manifestation of Lord Śrī Kṛṣṇa.
