I started reading Aryeh Kaplan's "Meditation and Kabbalah". Got to Chapter three (Rabbi Abraham Abulafia) so far and apart from being scared of the Hekhalot texts, I enjoyed the read. It resonated with me and my imaginary brain got at work.
The meditative technique that truly sounds most easy to accomplish is the meditation on a Divine name: focusing only on the name and repeating it a 112 times (why exactly this amount of repitions doesn't get explained) and (hopefully) forgetting about everything else except the name is the aim.
How can I meditate on the Divine name if I am not familiar with the Divine name? Would 'haShem' or 'yud-hey-vav-hey' work?
A bit of background which probably gets deleted but I'd like to include it anyways: The book clearly warns from practicing the meditation from the sages of the east (buddhist-hindu meditation if I got it right) albeit mentioning that the systems are quite similiar in what our Torah teaches and expaining this with the fact that Avraham Avinu fathered the eastern nations with a concubine of his. I personally tried buddhist meditation a couple of times (using the 'oom' chant while listening to binaural frequencies on youtube) but it feels like it did nothing to me.
