It is said that the material world is a distorted reflection of the spiritual world, so unless the variety that exists in this material world, how is it possible that it exists here even if it is ephemeral?
The beings of the material world who strive to understand the true nature of the spiritual world are fortunate beings. Those on the contrary have no taste to hear the description of the spiritual world, show more interest in politics and the economy. They meet in conventions and discussions to solve the problems of a world where they will stay only a few years, and under the threat of death that can pick them up at any time. If they were a little more fortunate they seek to return to the spiritual world in their original home, where there are no ignorance, suffering, selfishness, anger and envy. Unfortunately they will wallow in material darkness. The poor materialistic world that is occupied by the political organization of a planet that is only dust in the immensity of this creation. The earth is compared with a mustard seed in a bag of such seeds. The materialist is lost in a thousand projects to be more comfortable. It loses its valuable energy for a property that does not last, because everything is fleeting in this world. The best he could do would be to return to the spiritual world after leaving his body.
It is not possible to reach the spiritual world after having developed to a high degree, all desirable qualities. Be good, calm, peaceful, nonviolent, respectful, humble, kind, generous, compassionate, magnanimous, just, right, impartial, consider the consciousness of God as the major objective of existence, equal to all beings and love them all with equal love. Know that everything belongs to God, to love him, worship him, obey him, do his own will and serve with love and devotion.
The trees are all trees to wishes, which can get everything you desired, the soil is composed of philosopher's stone and the water is nectar. Every word is a song, every step is a dance, and the flute of Krishna is accompanied gestures at all times. Everything shines with its own light, comparable to that of the sun and moon in the material universe. In this supreme stay, sourabhis cows flood the land of milk. Since every moment is put to good use, there is no past, present or future.
In truth, the beings always absorbed in Krsna consciousness in pure devotional service, are given the chance at the moment of death, to get the company of Krsna in one of the material world universe because Krsna Entertainment occur constantly in this world or another. Just as the sun pours in turn its light on all places of our planet, Krsna-lila, or the Advent and transcendental pastimes of Krsna is perpetually manifest in our world or another. Devotees mature, having reached the perfection of Krsna consciousness, as soon as they left the material body are being transferred in the universe, whatever, where Krsna appears. There they get their first chance to live in the personal company, direct, Lord. This "training", we can see it in Vrndavana-lila Krsna on our planet. So Krsna does He revealed to the people of Vrndavana the true aspect of Vaikuntha planets, so they can know their destiny.
Krsna showed to them the spiritual world, eternal, endless and all knowledge. We find in the material world, various forms of body, sometimes high and sometimes low, and according to these forms, know different. In the body of a child, for example, it is not as perfect as in an adult human body. In all forms of life are distinguished various levels in aquatic beings, plants and trees, reptiles and insects. Birds and beasts, civilized and uncivilized. Beyond the human form are the demigods of Caranas and Siddha up inhabitants of Brahmaloka, home of Brahma; among the demigods themselves manifest different degrees of knowledge. But beyond the material world, in the "atmosphere" Vaikuntha, all beings also have full knowledge. There on the Vaikunthalokas or Krsnaloka, all without distinction, are fully engaged in devotional service to the Lord.
As confirmed in Bhagavad-gita, enjoy knowledge in its fullness is to know Krsna as God, the Supreme Person. The Vedas and the Gita teaches that in the brahmajyoti, the "atmosphere" spiritual, there is no need of the sun, moon or the electric force. There, all the planets themselves produce their light and are eternal. The spiritual world, bathed in that brahmajyoti, knows neither creation nor annihilation. The Bhagavad-gita also confirms that beyond the material world is an eternal universe, spiritual, where everything exists for eternity. The conditioned souls may have knowledge of the spiritual world by great sages already beyond the influence of the three gunas, the modes of material Nature. Unless you are firmly established in the absolute level, understand the nature of this spiritual world is impossible.
