Hi everyone,
You people are talking about two different things.....
1. Do we need or can we have a common philosophical base for all humans?
2. What does the word 'Spirituality'' mean?
1. It is not that we 'need' a common base. It is not a personal wish of anyone. It is that we in all probability, HAVE a common base.
We have a common anatomy, a common physiology, a common evolutionary history, a common genetic history....and so on. We also have a common psychological and mental pattern. People of different cultures and regions even have common NDE's.
Even with several cultural and historical differences we all today share a common moral and ethical system. Most people around the world have largely uniform ideas of right and wrong and it is converging more and more every day.
So there should also be a common future and a common purpose and pattern to our spirituality and our life goals. It is true that different religions seem to have different teachings but the similarities are obvious and many more. This is why it is important that we try to find commonalities in religious teachings and see if a uniform base philosophy emerges.
And from even rudimentary efforts we can see that there indeed are commonalities among the secret teachings. We have already discussed them many times.
2. As to what the word 'spirituality' means... I think too much is being made of it. Words evolve and are used differently in different generations. Don't get stuck on that.
