12, 24 and 36 Strand DNA Activation are 3 parts of the DNA Activation Series..those are not Reiki or a healing system, but for a personal empowerment and the energies are meant for personal use only. From the Manual - "With 24 Strand DNA Activation you will progress toward a higher consciousness and activation of additional dormant DNA strands and multi-dimensionality integration will occur."..frankly- I vote for all 3 of these attunements (12, 24, 36)..imho, it is worth to give them a try 👍
