The fourth chain, fourth round, the third globe was on planet Mars. Since Mars was the physical globe, it is logical to say that on Mars we developed a human kingdom. What kind of life was there for different kingdoms and especially human kingdom?
I have not come across much about the nature of the human kingdom on the previous Globe (Mars) in Theosophy. From the little I have read, the human kingdom in Mars were very energetic, impulsive, worked in great bursts of energy in last moment (when matters got delayed) and were greatly emotional or passionate. They had very little planning and worked in outbursts. I think I also read somewhere that hey were of shorter built and had wider chests, but I dont recollect where I read this.
