Your most fundamental fears are inherited
Your most fundamental fears, the ones that grievously spoil your quality of life, the ones that paralyze you completely, happen to be fears you inherited from your parents.
If you check your parents behavior, if you recall family memories from your childhood or simply inquire with your parents, you will find these same fears governing their behavior too, sometimes they will be tacit, sometimes under different disguises, but essentially they will be of the same fear nature, the same fear energy.
You cannot trace the roots of these fears
Your most fundamental fears seem deep rooted but actually if you observe them impartially, you will find out that you cannot trace them to any source, any traumatic memories, to any deep mental roots. This is the reason why I prefer not to call them "your deepest fears" but "your most fundamental fears", they have no deep roots, they have no circumstantial roots at all.
So what are they? They are simply isolated clouds of conditionings you inherited, as is, from your parents.
At first, it will seem to you very frustrating to have, on one hand, such dominating emotions in your life that influence so strongly your behavior, your choices, your decisions, and on the other hand, have no control over them, being completely unable to analyze their causes, unable to trace their roots.
What science has to say about it?
Scientists have discovered that at the back of the brain, located deep within the medial temporal lobes, there are tiny almond-shaped groups of neurons which are related to fear. They called them Amygdala.

The Amygdala is the dark side of the brain in which your frightening memories reside, the abode of your most fundamental fears.
These groups of neurons with the fear attributes imprinted in them are inherited from parents to offsprings. It was found that brothers and sisters growing up and living in different geographical locations felt the same emotional pains and were afraid from the same things.
Unless treated properly, these fundamental fears coded in the Amygdala may pass intact from generation to generation for eons.
So how one can handle these fears?
As said before, trying to analyze and track these fears to their roots is pointless as they have no apparent mental causes in your current life experiences.
There are basically two effective approaches to handle these rootless fundamental fears which usually are combined together into a successful whole process. These two approaches are healing and spiritual awareness.
- Healing
There are certain healing and other supernatural techniques that may prove effective to some extent in weakening and even displacing these inherited fear conditionings. These include Theta healing, The Light Language and many other. But even if you choose this approach to handle your fundamental fears, you cannot avoid the other approach.
- Spiritual Awareness
The other approach is spiritual awareness: observing and accepting these fear conditionings, respecting them instead of pointlessly fighting and rejecting them. Learn to live side by side with them instead of trying to uproot the rootless. Understand that you have no reason to feel guilty about them as you simply inherited them from your parents, and they, in turn, are also not guilty as they acquired them due to life situations or also inherited them from their parents and so on.
By observing and accepting, you start to extinguish the accumulated layers of fundamental fear conditionings, one after another. Conditionings strengthen when being unobserved and resisted and weaken when observed and fully accepted.
Observing and accepting the fears, they will weaken and weaken until they are no more. But then their expiration will not be important to you anymore. If you truly and fully accepted them then you are already unattached and unaffected, free from their impact, being able to live side by side with them and still be happy.
You realize then that it was not you that was affected by and attached to them, it was again your mischievous mind.
Try it and you will experience it by yourself.
Handle the fundamental fears and so your quality of life will improve. Handle the fundamental fears and so you will not pass them to your children, as your ancestors did. You will finally disconnect the fear inheritance chain coded in the Amygdala.
