The state of mind and its effect on circumstance.
Captains with access to the far east of the world brought forth 7th century legends of an infamous assassin tasked with the responsibility of putting down the regional level 4 Gurukkal Master.
The formidable skills of such a master or Kalari Gurukkal as they were often called, usually translates to doom for most challengers.
But this assassin was no ordinary challenger. He had with him special mixtures from far giving him the ability to reach beyond his physical limits and exact destruction from a safe distance. A novel advantage at the time.
The assassins mind, filled with rage and anguish, cut across the Mahanadi to claim his prize, ignoring the spiritual significance of the regions he crossed. And here he made a tactical blunder.
The Mahanadi river in the region now known as Katak or Cuttack was rumored to reflect the states of mind of all who cross. Reflecting in this case the very powers he possessed delivered by children whose lives he was responsible for. The battle raged by the banks of the river for three days and three nights with blasts of light and thunder heard as far as what is now known as modern day Puri. The assassin had no choice but to retreat in shame.
Relevance for today: Your world is a reflection of your thoughts. Perhaps not with results as quick as illustrated above but no less dramatic. you must consciously monitor your thoughts to prevent undesirable realities
