merkaba meditation

Dear friends - i am practicing the merkaba meditation according to drunvalo melchizedek since some months. i am using drunvalo's guidance from both his original book and cd. Althought in his book he explains every step in detail, he advices to attend a live workshop to learn the proper meditation. so i was wondering if i will be able to activate the merkaba through the written and spoken guidance at all or whether some crucial information is missing there. the meditation itself is quite complicated as you might have experienced yourself. you have to focus on various things with body and mind contemporarily. it surely takes time, exercise and patience, which is fine! so i was wondering if there is somebody in our community who has experience with this type of meditation? if so, I would love to share with you.

Love & blessing to all of you, *akasha*
