“Courage is resistance to fear, mastery of fear, not absence of fear”.
Mark Twain

The path of spirituality also needs courage to learn unknown and you may come across many bitter truths about self from past lives and other unknown fears as delusion evaporates. This path is lone path there are many travelers on this path but all are at different point in time and space as per their spiritual development. Certainly you will get help guidance and even inspiring energy from within and from some other higher spiritual practitioner, but still you have to cover the path alone. Traveler needs lots of courage to overcome fear of unknown and temptation of martial world. And you also need constant physical, emotional and psychological adjustment.

 But after some development you will find yourself safe in unknown divine hands of Supreme Being. The most fascinating thing about this path is that you are never losing.
What you gain by practice will be yours for ever. And even if this physical
aspect ends (end or death of physical body) before self-realization (salvation/moksha/liberation); in your next incarnation you will start your journey from the point where you have left. Thus if you start your journey on spiritual path be prepared to face many unknowns and even very scary occurrences. But still it leads to eternal
peace and joy. BE HAPPY IN YOUR PRESENT; WHATEVER IT MAY BE.
