Krishna accepts even an enemy's service; through bhakti alone, not speculation, He becomes eternally visible.Listen — Srila Prabhupada Uvaca
Śrīmad-Bhāgavatam 6.1.31 — July 16, 1975, San Francisco 750716SB-SAN FRANCISCO [31:46 Minutes] SB-06.01.31_750716SB-SAN FRANCISCO Nitāi: vikarṣato 'ntar hṛdayād dāsī-patim ajāmilam yama-preṣyān viṣṇudūtā vārayām āsur ojasā [SB 6.1.31] [03:27] "As the order carriers of Yamarāja were snatching out the soul from the core of the heart of Ajāmila, the husband of the prostitute, the order carriers of Viṣṇu forbade them with great resounding voices to do so." Prabhupāda: vikarṣato 'ntar hṛdayād dāsī-patim ajāmilam yama-preṣyān viṣṇudūtā vārayām āsur ojasā [SB 6.1.31] So when the order carriers of Yamarāja were trying to take away Ajāmila from this world to the other lower planetary system... Below this universe there are many planetary system. They are called Pātāla, Tala, Atala, Nitala, Talātala, Rasātala, Pātāla—seven layers. So below that layers there is hellish planets.
Just like up, there are heavenly planets, similarly, down there are hellish planets. So Yamarāja, his kingdom, his jurisdiction, is within these hellish planets. So one point is very important. People are sometimes amazed, "Where is the soul?" Now it is clearly said here, hṛdayāt: "from the core of the heart." Therefore soul is existing within the heart. And the Paramātmā is also existing.
The yogīs, they want to see. Although they are, Paramātmā and jīvātmā, sitting side by side, and He is dictating, but on account of our foolishness we cannot see Him, neither hear Him. Antar-bahiḥ. He is within and He is without, but unfortunate as we are, we cannot see Him either within or without.
How it is possible? Just like a family member, your father or brother, is playing on the stage, but you cannot see him. Somebody is pointing out, "Here is your brother, dancing." You cannot see him. Naṭo nāṭyadharo yathā [SB 1.8.19].
Just like a person dressed in dramatic performance, his relative cannot see him, similarly, Kṛṣṇa is everywhere, aṇḍāntara-stha-paramāṇu-cayāntara-stham [Bs. 5.35]. Simply one has to make his eyes purified to see Him. Then he can see always Kṛṣṇa, within and without. Premāñjana-cchurita-bhakti-vilocanena [Bs. 5.38]. This seeing is possible only in bhakti, not in jñāna, karma.
No. No other way. Premāñjana-cchurita-bhakti-vilocanena. No other method is prescribed.
In Bhagavad-gītā also, it is said, bhaktyā mām abhijānāti yāvān yaś cāsmi tattvataḥ [Bg. 18.55]. If you want to know Kṛṣṇa as He is, then you have to know Him through bhakti-yoga, not any other. Others, they may go on speculating for many, many millions of years. Still, they will not be able to understand. panthās tu koṭi-śata-vatsara-sampragamyo vāyor athāpi manaso muni-puṅgavānām so 'py asti yat prapada-sīmny avicintya-tattve govindam ādi-puruṣaṁ tam ahaṁ bhajāmi [Bs. 5.34] For many millions of years running in the speed of mind and air, not this aeroplane speed...
