Most of what we do in this lifetime to express our spiritual nature is built on many past lives.
We have lives where our karma is all about learning and practising a spiritual skill and developing our consciousness. In some past lives we may have had the karma to prepare our chakras, aura and bodies, then learn forms of healing. We may, lifetime after lifetime, have learned how to use specific chakras such as the third eye, or other chakras we would use in later lifetimes.
These past lives can have been way back, further than Altlantean root race times, and in Lemurian root race times. Some of the lives can have been in time periods we know something about.
If you are fairly good or very good at meditation without any props (such as chemicals or music) it is likely you would have had one or more past-lives as a Buddhist, who were experts at meditation, the mind and what could be done with the mind. Similarly, you could have had past lives in India with it’s remarkable ground energy, practising meditation techniques drawing on the rich spiritual heritage there of Avataric incarnations of Ram and Krishna and other teachings in the Hindu body of spiritual knowledge.
Some of the more advanced knowledge would have been very technical and complex, requiring a lot of study and practice.
People who are drawn to Atlantean energy techniques would have had at least one lifetime in that time period in the area of the world that was influenced by that culture.
Throughout human history going way back there have been so many cultures around the world for people to have had past lives in, that were beacons of spirituality. There were Shamanic traditions in Europe, Asia and the Americas. (A long time ago what is now Russia and Alaska were joined so people and animals could travel and migrate.) People who like herbs, for medicinal use, for meditation, astral travel and meditation would have had lifetimes to build up knowledge and abilities. These and other lifetimes would be planned out on the inner planes between physical lives.
There are so many places in the world where it was possible to learn to use the body and chakras and aura for healing. A clue to Lemurian energy handling techniques comes from massage techniques and exercises done before massage in the huna tradition found in Hawaii. This knowledge extended throughout Polynesia (and there is a lot more to it than what is mentioned here). Other places where people could incarnate in past lives to learn how to use energy and heal would include China, in the Taoist tradition, in the Muslim Sufi traditions (think of the poets Rumi and Hafiz), in the Celtic Druid religion in the British Isles (very deep spiritual knowledge and think of Stonehenge and other stone circles). People could have had past lives in early Christian communities before the corruption at the centre of the Roman Catholic church, and in some Orthodox communities (knew a lot about breathing techniques). The Ancient Egyptian culture was a place where people learnt about using energy, after the Atlantean period. People may also have had past lives learning Jewish mysticism and practising spirituality based on Kabbalah. I really don’t know much about spirituality in Africa, other than there must have been some traditions and teachings as there are still witch doctors and there was great skill with herbs.
What it would have been like to have one or more past lives in a culture such as the Native American culture before the destructive arrival of Europeans. The cultures had a deep spirituality which guided life and the relationship with Nature. There are very likely to be people alive today who did have past lives in these cultures.
The interests and skills that spiritual people have who are alive now can sometimes but not always give a clue to past lives of a spiritual nature and the kind of religions and spiritual practices they have been involved in. All that training got them to the point they are now at.
