The centre of human culture and personal life is spirituality and religion.
Of course Christianity is about dead today.
We need the eastern thougths as it is only in some of these religions the metaphysical truths have been explained in letters.
Most of the eastern religious movements in the West are too much focused on the indian, tibetan form , so much, that some of them seem unable to explain even the most basic core of metaphysics behind the religion!
They want the tibetan incence and the singingbowls, but have they heard about the four noble truths?
Religion today is mostly an identity procuct, that people take on to themselves to look cool.
The yoga classes says : "You can get all these things, if you pay us your money, self confidence, happiness and success in your career." But they never seems focused on the most important, the unspoken wisdom about your existence.
In reality humanity have already created the complete metaphysical science about existence in the upanishadic litterature and in early buddhism, but it need to be shaped to a western mode of life without loosing its essence, like it does with the New Age-movement.
Some says islam should shape the modern world into something more appriciateeable. Though, that culture is so focused on the dogma of the letter and on the inherent moral truths, just like the fault was with christianity.
If you ask me, people should be forced to convert to buddhism. They are already atheist, so all they have to realize is the selflessness to accomplish that.
