In my opinion the human organism is designed to handle stress.
Man has probably always been subjected to stress, whether it is evading the clutches of a wild beast, or getting out the way of an out of control motor vehicle.
Or, feeling stressed during a heated tribal disagreement, or a fast approaching work deadline.
In my opinion, the problem is not the experience at the time – the body can handle these things – it is the stress does not cease when the actual experience finishes. That is, thought continues the experience long after the event.
An old Eastern parable that goes something like this (excuse my inaccuracy of the actual story, but the thrust remains the same):
Two monks were at a river ready to cross and found a pretty woman on the bank who was afraid the running water may sweep her to her death if she attempted to make the crossing. One of the monks offered to carry her across, much to the consternation of the other monk who believed doing so contravened their moral code.
However, they all managed to cross safely, the woman went her way, and the monks continued walking in silence.
Much later, the monk who was against helping the woman said to his companion, ‘you know you shouldn’t have done that.’
The other monk replied ‘I put her down on the riverbank more than an hour ago, but you are still carrying her now’
A nice story I think.
Myself, various sages and seers (or sundry ‘crazies’ as perceived by many) over the years have said that life is a series of independent events, that it is thought, that we believe to be ‘I’, that links them together.
Furthermore, the sages say that ‘freedom’ or ‘enlightenment’ or ‘acceptance’ is not some state of perpetual bliss, because bliss is but another experience of thought.
No, it is that whatever event that occurs in life, that experience has a life of its own for the duration of the event.
That life includes whatever thoughts and emotions that may incur, from unhappiness to happiness, anger to joy, etc, etc, and all the associated neuro and hormonal activity during that event IS harmonious functioning of the body. Then the experience is finished.
But, when whatever the experience may be, is carried on beyond the actual event, then the organism undergoes prolonged stress to a greater degree than otherwise would occur. And health and wellbeing can become compromised.
So to use an analogy: some experiences are like rain clouds, dark and heavy. Other experiences are light and airy. But all clouds are part of the sky. They come, they go. It’s just that we try to hang on to some experiences and be rid of others.
