Man is not mare a biological entity or so, core essence of being human is entirely different than what appears to be in gross mode.
Indeed there is a hidden core of human personality which lends meaning to life and man remains at large till attain so.
Reality of spirit is a distant subject for normal being but for human it is subject to perceive and interact with, spirit is nothing but a ray of light and source of light is God.
Spirituality alone is the subject that lends truth and inspires one to attain so and conscious communion with is the subject that designated for spirit.
May lord bless all.
Thanks please
