The use of Yuck and Ah as initial insitinctive or intuitive responses is common amongst all capable minds and they both illustrate a wrinkle in the epigenisis of our emergent understanding in one time forward lifetime.
The sight and smell of blood may create viseral responses that are transgenerational illustrating our impotence in the present while the baby's smiling eyes open a profound sense of willing receptiveness we often associate with the first signs of true love in the life of a parent.
The child that becomes the serpants tooth and the blood that becomes precious evidence of vivacious life are high contrast examples of how emergent knowledge flows in one time forward lifetime.
If we are clear minded and reflect upon our own lifetime we can see clearly that there is no reason from our own experience to imagine that a child should be able to understand and empathise fully with parents lived experiences or inherit their evaluations of life among the hoi polloi. For countless generations housholds have been commited to being considered respectable in their communities and in so doing have rejected the nature of their own children, using yuck responses to there own children, while in search of the affirmations of relative strangers.
The curtailing of willing receptiveness by pride and status was uncovered as inherent at the Institute Of Psychosynthesis in London among their students and staff at the turn of the Century, when they attempted to outline a triphasic model of spiritual development among the Institutes members.
A more sincere and willingly caring group of people you are unlikely to meet in any one place in your lifetime yet the unseen systemic pressure to belong and excel created a hidden flaw that was an existential threat to the thesis that was being applied in the learning at the Institute.
