This is why Krishna, God, the Supreme Person, specifies: This realm, from which no one ever returns to this material world, is the supreme abode.
Krishna, the Supreme Lord, is the refuge and abode of all that exists. In His body rest all the galaxies and all beings live.
Truly, nothing exists outside of Krishna, God, the Supreme Person, nor is anything separate from Him.
Quite naturally, we imagine the spiritual world in relation to the universe as we know it, with its sun, moon, stars…
However, the spiritual world needs neither the sun, nor the moon, nor fire, nor any other luminous energy to illuminate it, for it is luminous in itself, already bathed in the radiance emanating from the divine body of God, the brilliant light irradiated by the Body of the Lord. This realm, this abode of the Lord, unlike the material planets, is easily accessible. It is called Goloka, and Lord Krishna never leaves Goloka, His realm. Yet, from where we are, we can approach Him, for it is precisely for this purpose that He chooses to manifest in this world His true form, all knowledge, bliss, and eternity.
From Krishnaloka, or Goloka Vrindavana, the supreme and original place, the planet of the Supreme Lord, emanates the dazzling light of the spiritual world. In this radiance bathe the countless spiritual planets, of which the Lord teaches that whoever reaches them never returns to the material cosmos. There, there is no suffering, no birth, no sickness, no old age, and no death, which are characteristic of all the material planets. Krishna, God, the Supreme Person, is the sole Monarch of the entire spiritual realm, three times larger than the material cosmos, and all beings who dwell there are conscious of Him. Although always present on His own planet, Krishnaloka or Goloka Vrindavana, larger than all the spiritual planets and the material cosmos combined, which He never leaves, He simultaneously reigns over each of the spiritual planets in His various divine forms.
Such is His omnipotence.
There are countless spiritual planets called Vaikuṇṭha in the spiritual world, and on each of them reigns Lord Krishna in the presence of His entourage and all that belongs to Him. In the spiritual world, everything is eternal. The Lord tells us that before creation He already existed in His fullness, with all His divine perfections: perfect beauty, wealth, power, wisdom, and renunciation. He exists in all His power, with all perfections. He simultaneously dwells in the realm of Vaikuṇṭha in His personal, original form and in the material universe as the Supreme Soul, also called the Holy Spirit. Despite His eternal and perfect presence in Goloka Vrindavana, in the realm of Vaikuṇṭha, He is at the same time omnipresent throughout the entire material cosmos. This all-pervading aspect of the Lord is called the Supreme Soul.
