Mundane existence is itself a kind of fear because in all mundane bodies the effects of birth, death, old age and disease always keep a living being compact in fear. In the mundane world, there is always the influence of time, which changes things from one stage to another, and the living entity, originally being avikāra, or unchangeable, suffers a great deal on account of changes due to the influence of time. The changing effects of eternal time are conspicuously absent in the immortal kingdom of God, which should therefore be understood to have no influence of time and therefore no fear whatsoever. In the material world, so-called happiness is the result of one's own work. One can become a rich man by dint of one's own hard labor, and there are always fear and doubts as to the duration of such acquired happiness. But in the kingdom of God, no one has to endeavor to attain a standard of happiness. Happiness is the nature of the spirit, as stated in the Vedānta-sūtras: ānandamayo 'bhyāsāt—the spirit is by nature full of happiness. Happiness in spiritual nature always increases in volume with a new phase of appreciation; there is no question of decreasing the bliss. Such unalloyed spiritual bliss is nowhere to be found within the orbit of the material universe, including the Janaloka planets, or, for that matter, the Maharloka or Satyaloka planets, because even Lord Brahmā is subject to the laws of fruitive actions and the law of birth and death. It is therefore stated here: duratyayaḥ, or, in other words, spiritual happiness in the eternal kingdom of God cannot be imagined even by the great brahmacārīs or sannyāsīs who are eligible to be promoted to the planets beyond the region of heaven. Or, the greatness of the Supreme Lord is so great that it cannot be imagined even by the great brahmacārīs or sannyāsīs, but such happiness is factually attained by the unalloyed devotees of the Lord, by His divine grace.
