Ok I'm going to grill you for a minute pianoperformer, so hold on..
Being more specific, what about spirituality do you want develop more?
What exactly do you want to experience as a result of developing spiritualy?
How will you know you've develop it?
I think this is where being specific and goal oriented comes in, so you can know you're making progress and when you have achieve it or achieving it.
If you would like to communicate with spirit guides, for example, it may take a specific technique/meditation and way of directing your mind in order to do this;
Think of it this way with these analogies... you can take up wrestling (analogy- practicing awareness) to participate in sports but that will not neccessairly mean you will be good at playing basketball (analogy- raising kundalini) ... exercise, (analogy - meditation) is required for both sports, but just because you exercise for wrestling doesn't mean it will make you good at basketball, although more capable of playing it.
That's my view so far, if anyone else has view or idea too, let us know please...
