On mother earth, existed Mount Everest then why not every human being climbs Mount Everest or why has one not climbed Mount Everest until now! The reason is simple, human beings have been provided with free will exercising which human beings can choose their goal of life. Not necessarily the goal of all human beings is self realization!
No doubt the ultimate goal of life for all human beings always remains reaching state of self realization but for that God Almighty ordained a long journey of 1.1 million manifestations in human form. Where was the hurry?
Spirituality is one field that can never be enforced on any human being on mother earth. So is not permitted by God. Religious practices can be enforced but not spirituality.
The reason is simple. The journey of spirituality is an inward journey towards the spirit, soul atman existing in heart. We cannot expect a student of class one indulging or fiddling with books of class 12. The result would be zero. The same is the case with spirituality.
All human beings on mother earth stood at different karmic indices. One may appear young six years of age but on spiritual platform one may be nearing state of self realization. One 80 years in age may have not yet started spiritual journey. External appearances in field of spirituality can be deceiving. The spiritual age of a person can never be determined.
As the journey of spirituality demands indulgence in contemplation (chintan) most human beings world over avoided indulgence in chintan (contemplation), something difficult to practice.
As ordained by God we can indulge in spirituality in present life time to reach state of self realization or keep rotating in endless cycles of birth and death again and again.
When around nine years of age I finally decided to end this mindless rotation in cycles of birth and death! And hence started my spiritual pursuit of life!
