The below technique seems to call up Fe, at least for an ENFP.
It may be of most value to those who have Te rage, overwhelming Fi emotional pain and fluctuation, or Fi users who suffer from chronic fatigue, chronic pain or autoimmune disorders.
I am content to think thoughts in my head. I cringe at sharing this.
I suspect Fe users have increased basal cortisol levels relative to Fi users.
1. Relax your face.
2. Release tension (Te for an ENFP)
3. Construct a mask.
a. Make a fake smile. Only your mouth. Only a very slight smile. Too much will be tiring. Intentionally relax the muscles around your eyes. The eyes are very important. Real smiles use the ocular muscles.
b. Fix the mask. Let it gently respond, but only very slightly. Your eyes are free to move. Your mask/eye muscles are not. Donít move your brow, donít tense your eye muscles, little movement of the smile.
c. Mentally detach your mind from the mask. Your mind is free to think anything. Your mask must not move in response. It is a barrier.
d. Your thoughts are not your mask.
4. Construct a mental mantra to remind you to not allow the other to see your pain. Even if you scream in emotional agony internally, do not allow the mask to change.
5. Do this for several days. Constant.
The first day was emotionally painful and confusing, nonauthentic. On the second day the internal pain was gone. A sense of relaxation and calmness permeated. By the third day I did not need to smile anymore. Instead just maintain the mask. By the fourth day the mental state flowed very naturally and is pervasive.
By the second week I can call the mental state of Fe calmness/affection when needed. Fi is very quiet but peeks up now and then. It can be called it on demand or quelled. Te quibbles with Fe. It is marked by a mild increase in anxiety as it surfaces. Ne has become Ni, although I really am uncertain what to do with it.
My hope is this is of value to a few.
