Then to be spiritual is to live and express that vital force to the best of our abilities. There are numerous centers for spiritual learning and advancement. In the same breath there are as many different strands of spirituality and organizations to match. Many bookshops stock spiritual authors as does the internet. In a word - nothing.
Spirituality comes from within.
You don't need to go to a certain place at a certain time. You just need to believe, have some time to think and be at peace. It doesn't matter. You don't need to take part in organized religion to be spiritual. Spirituality is very personal and very diverse.
