Seven Chakra or Zones & growth of Psychology.
Many people become successful in their life but after reaching to the top they committed suicide.
Why? What is the reason behind such achievement?
They have used only one wing to fly in the sky, while even a bird needs two wings to fly in the sky.
Meditation is the other wing, they have not bothered to grow it in their life while climbing on ladders of success in corporate world. In material life it needs to be just kept growing at very slow pace, so that when one embarks upon the spiritual journey or inner journey the much needed other wing has grown sufficiently to keep one flying in the sky.
