I say:
One cannot get the answers for the purpose of life until one looks beyond the boundary of one's life. Many may not ever understand the purpose.
However, we can aspire. The very purpose of human birth is to obtain permanent and everlasting bliss. The urge will continue until the bliss is achieved.
Spirituality is all about solving the mysteries of life.
You say:
'Oh I am not able to sit relaxed even for a few minutes. Problems fill my life: money problems: health problems; worries.' Along with these, the condition of facing competition in business with the thought, 'if I relax, I may be pushed far behind. In the midst of all such struggles, do I need spirituality at all?"
Wherever I go, people surely ask me questions in this manner.
The answer for this is: yes, we do certainly need spirituality.
Just like the traveler, in this story, many live their lives knowing certain things superficially. That is why their searches continue to meet with failures.
Who are you? How many are the wonders lying dormant within you? How to live life joyfully? Why our lives or our relationships do not proceed as we desire them to? How to make the desires come true?
We do need spirituality to discover answers for these questions. Spirituality is the only path that reveals to us the treasures lying hidden in ourselves in the potentiality of our mind, body and being.
Many of us do not know how to really enjoy whatever property and name and fame that we now possess. If the quality of real enjoyment increases in us, we will actually be far more joyful in these matters.
Spirituality is that path which enables us to get contentment and joy which we do not get after even achieving many great things in life.
We will be continuing to lose a wonderful part of our life if we do not set apart at least half an hour each day for spirituality in search of a blissful life.
Therefore, there is no place at all for questions like: Why spirituality? What for spirituality?
Spirituality has actually become an essential subject for everyone in this fast paced mechanical world. An inevitable subject!
