I have an extensive recall of many of my past lives. It is difficult to recomend a technique in particular but a good starting point is learning how to meditate
There is no one technique, it is a process that starts by accepting it is possible and reconecting to all that you are in order to remember. Most of the good techniques will cost you money.
Most of the information is in your cells and in a sphere around your mental body called EGO epigenetic overlay
In the keylontic sciences group in this forum I have posted a protective technique which is very useful before meditation, it is called the epsilon sequence
