This is the eternal spiritual world.
At the top we see Krishna, the Supreme Personality of Godhead, a transcendental
cowherd boy at play with His topmost devotees. These devotees are so
totally in love with Him that they even forget He is God.
Being God, He can expand Himself into unlimited forms without diminishing

expansion who plays as His brother, another cowherd boy.
After Balarama come the Vishnu or Narayana forms, manifested for those
who do not want to forget that He is God, and who prefer the more formal
worship of this majestic four-armed form.
But some become envious of God’s position and want one just like

give these souls a place to try to fulfill their desires, and to ultimately
learn that such a choice cannot bring happiness, the Supreme Lord again
expands Himself as Maha-Vishnu (Great Vishnu). Maha-Vishnu lies down
