My name is Terence and I am new to meditation and to Buddhism, and was interested in finding a site that teaches online meditation or has really good and relaxing guided meditation videos. Do you know of any such site? What you even use it, if it existed? I want to find an online community of mediators. Should I build it? I really want it.
I would advise finding a face to face teacher in your local area to meet up with as the preferred option, so try to find a local teacher in your general area! although there are plenty of guided meditation tracks for varying degrees of experience around maybe the Take10 program would be a good starting point for you? http://www.getsomeheadspace.com/
you do not have to sign up and pay for the other programs although as an introductory resource it is quite good.
There are plenty of experienced & knowledgeable practitioners here so if you have any questions you can ask and get advise.
Although not to put a downer on you exuberance for meditation, you should get more experience before creating somewhere for meditatiors.
