Hi everyone,
It is generally agreed by philosophers and thinkers since ancient times, that our objective understanding of the world is limited by our senses, our brain configuration and so on. In recent times even some scientists are beginning to accept this as a fact of life.
In other words,our objective understanding of the world has natural boundaries and limitations that cannot be surmounted (even with the help of technology). Our 'understanding' of the world can therefore be seen as illusionary. There could be many hidden aspects of reality that are outside our capabilities and our view of the world could be like shadows on a wall.
However, contrary to scientific thinking (until recently) religious/spiritual people have long understood that while the objective world could be illusionary, we can access certain underlying aspects of reality through internal mechanisms such as introspection, mind control and so on. It has long been understood that delving into our inner world is more revealing and fulfilling than all the discoveries we make of the external world.
Some people of science however consider subjective aspects of life as mere imagination and mental imagery created by the brain, which are of no importance in understanding reality. This is a mistake.
No doubt, our imagination, instinctive impulses, desires and so on can create significant noise and clutter that can be an impediment to inner development. This is why exercises such as Yoga, meditations, rituals and prayers are prescribed so that the clutter and noise can be reduced and we can undertake the inner journey meaningfully.
That our subjective aspects can be important (in fact more important than objective aspects) is now beginning to be realized by some people of science. Please refer to my thread on panpsychism, the hard problem of Consciousness and IIT.
Just some thoughts.
Cheers
Sriram
