Past life regression techniques Is there anyone knows and has experience in past life regression? How can I do to recall my past life memory? Thank you.
There are two methods for seeing past lives:


Through phenomena, and
Through time (or chronologically)


The 'through phenomena' method is not exactly a method. It is more of a chance thing, but it is also easier. In this case, a sight (or other sense-stimulation) occurs and one has a deja vu experience ("I've done this before"), but without the doubt. At this time bending down the mind (or focusing on, or concentrating on) the feeling and the phenomena, a previous occasion when this phenomena occured will come to mind. If pressed further details will appear.

Then you will have to fight your programming and half the other Buddhists in the world who tell you that there is no such thing as rebirth and that you are just imagining things. Would that I had a mind with such an imaginative power!

The chronological method is by way of a yonisomanisikaro=like tracing back of the events of this life from the present moment back to birth, back through one's time in the womb, the time of one's conception, to the previous life. This is rightly an aspect of your setting up of mind (satipatthana). It is also exactly similar to Casteneda's Don Juan's 'recapitulation' method where you start in the present moment, and review every detail to extract yourself from all attachments found there and then move back in time. 

More or less unrestricted chronological viewing Past Lives is one of three 'visions' that are obtained by the Arahant, but anyone can experience awareness of past life events through phenomena.

In Buddhist studies you will find that viewing past lives is to be accomplished from the fourth jhāna. But this is just the optimal method.

The formula for the Buddhist seeing past lives can be found in multiple suttas worded similarly to:

He recollects a variety of former habitations,
that is to say

One birth,
two births,
three births,
four births,
five births,
ten births,
twenty births,
thirty births,
forty births,
fifty births,
a hundred births,
a thousand births,
a hundred thousand births,
and many an eon of integration
and many an eon of disintegration
and many an eon of integration-disintegration:

'Such a one was I by name,
having such and such a clan,
such and such a colour,
so I was nourished,
such and such pleasant and painful experiences were mine,
so did the span of life end.

Passing from this,
I came to be in another state
where I was such a one by name,
having such and such a clan,
such and such a colour,
so I was nourished,
such and such pleasant and painful experiences were mine,
so did the span of life end.

Passing from this,
I arose here.'

Thus he recollects divers former habitations
in all their modes and detail.

A helpful and cautionary Sutta which discusses the method for this and other powers is AN 9.35 (Hare's translation linked-to here:)
