In what sense are you asking about Holistic? There are many ways of approach such as in medicine, Gaia, gardening, farming, forestry, psychology, problem solving, life style, the environment and ecological issues..and more.
Thanks for replying.
Yes it is enormous, vast and very intresting to say the least.
In medicine,
treating patients as individuals and looking beyond their specific disease,
What today we call a holistic approach to medicine.
Holistic is not just physical, mental and emotional well being,
but spiritual as well.
The Rebbe says,
.....personal path you choose in life,
even these pursuits have a deeper intent and purpose,
in the words of the Mishna:
"I was created only to serve my Maker."
A person can only fulfill his G-d given mission by living in a holistic Jewish way....
So, yes it covers more or less all things.
One thing that caught my attention was that someone can be affected by some kind of ailment or other,
caused by something that happened years ago, even a knock on the head.
So holistic or "Wholeistic"
