I can quote, and you might also be able to relate to lots of examples to substantiate this argument.
For instance,I have spoken about the misconception of the concept of 'God' previously.It could be one.
Transcending in similar lines,let me tackle another close conceptual associate of the idea of God -Spirituality. I should better be attributing Spirituality to be the source out of which the concept of God was churned out, but as a misinterpretation!
Spirituality, by today's definitions, is a quest of something that is essentially not in our humane realms. It is a not a subjective entity, but an elaborate process of attaining a certain state of mind, where the mind is supreme, or enlightened.
Essentially, Spirituality as I have understood, was a mechanism conceptualized to nurture the 'self' to realize one's own potentials. Simple.
In attempting this,and to give the mind a better picture of what it is aspiring to become, a slightly exaggerated idea of the 'objective' was depicted, to serve as a signpost, or like a vade mecum. But,this exaggerated idea, with growing senility of the society, has come to be known as today's 'God'.
With so much of misconception shrouding the true sense of Spirituality, it definitely had to become the lucrative business it is today, attracting hollow humans.
Spirituality simply is a tool / a process / a methodology, helping the mind to realize and perpetuate one's potency, while mitigating the flaws.
Until we try to 'Know Thyself', we will continue to be slaves to every big thing that has gone wrong in the society!
