Learning from books to get techniques is ok. Like I said a technique you can get from anywhere books, articles, internet. I have taught people to meditate myself in under 5 min.
They’re all pretty simple really and consist of two steps:
- Focus on something and keep your focus there
- When you notice your mind has wandered of, bring it back to your focal point
I have used various objects like mantras, concepts, visualizations, chakras, AUM, breath, and senses, silence. I also tried new-age techniques like guided CD meditations, hemi-synch
It is not true that I have only learned from books. I first learned meditation from a spiritual teacher from the Brahma kumaris. I then attended some new age workshops and psychic development classes and learned various meditations like chakra and colour meditations, mediating on visualizations of violet flames, and trying to contact your spirit guide. Then I got more serious and learned different meditations from my acharya at the university meditation society from the Anandamarga Yoga tantra tradition. I was formally initiated and given a personal mantra at stage 1. Then a few months later I got to stage 2 and was given a mantra+breath synchronization meditation technique + a visualization to induce pratyahara. After that I learned the meditation on the crown chakra from from the local Sahaja yoga group and dynamic meditation from the local Osho group.
I had for about a year also a Gnostic spiritual teacher I saw every week in our local group who taught me dozens of meditation techniques, vowel sound meditations, duality meditation, elimination of ego meditation, focussing on the senses, chakra meditations, third eye meditations.
My learning is both from books, teachers and my own experimentation.
