ALL THIS PAIN IS AN ILLUSION
Having a high threshold for pain is just another way to express one’s calm ability to not mind what life throws at you. To be OK with anything at all means you will be even-minded at all times. To not be offended by anything is another way to look at it, another way to describe it.
In extreme cases, one can even endure what would otherwise register as excruciating pain with little or no reaction. An example in recent times occurred when Mahatma Gandhi once endured a surgery while fully conscious, even calmly chatting with his surgeon during the operation. In ancient times, the Yogi-teacher of Alexander the Great once walked into his own funeral pyre right in front of a thoroughly astonished Alexander and his army and calmly let himself be burned alive.
Such instances are of course rare but certainly serve to prove the point that when one is united to God, one realizes that all sensation is really an illusion. Pain, pleasure and everything in between is really as nothing. It seems real, but what seems to be is not what truly is.
All that we feel is just sensation—nothing more.
Realize that truth and nothing you experience will disturb you, not even your own death.
