No healing facilitator
of integrity should ever promise to "fix" all a client's
problems in one session. (And no client with any self-awareness
expects this.) "Instant healing" of everything simply
may not be possible because of the great complexity of factors
involved: negative karma across lifetimes, transgenerational
imprints (genetic core inheritance), and current-life habitually
negative thoughts, emotions and behaviors.
Regarding the dynamic interaction of life issues between embodiments,
literally: When you change something in the current lifetime
it affects all your other lifetimes. By the same token, if you
have afflictions in other lifetimes, these usually are also having
harmful effects on you in the current lifetime.
