This term, also translated as "insufficiency" and "disorder," appears in the Scriptures.
(1) The term often refers to a condition in which one's free use of the body is impeded by a bodily disorder or other such difficulties.
A body that had no disorder (fusoku) anywhere: Tsukihi bent it and caused you much trouble.
Sah, sah, God has not lent anyone a body that has any insufficiency (fusoku). What you call insufficiency comes from your own mind.
Osashizu, November 8, 1887, supp. vol.
The body is a thing lent. The mind alone is yours. God did not lend you a body that has any insufficiency. You would be mistaken to think that the body had any insufficiency. It is all the mind's feeling of insufficiency that is manifested in the body. If only the mind is cleared, the body is free of all insufficiency.
Osashizu, around September, 1888, supp. vol.
All human beings are God's children, and all are things lent by God. I have not lent anything that suffers insufficiency.
Osashizu, 1889, supp. vol.
(2) The term also refers specifically to the mind's feeling of insufficiency, which is the opposite of satisfaction. The mind characterized by dissatisfaction is a mind that lacks joy. A Divine Direction says, "Dissatisfaction (fusoku) sets in motion the wheel of dissatisfaction" (Osashizu, January 8, 1898). The mind dominated by dissatisfaction, which clouds the capacity to receive God the Parent's providence (Osashizu, February 6, 1904), not only blocks our own Joyous Life but also gives rise to a feeling of dissatisfaction and insufficiency in those around us. Our dissatisfaction stems from not knowing that we human beings are enabled to be alive by God the Parent's providence and that we are receiving God the Parent's blessings according to our states of mind. Dissatisfaction also arises from greed. It is taught that, if we truly understand that the human body is something lent by God and savor a sense of joy and gratitude for it, the feeling of dissatisfaction and insufficiency will disappear, thereby allowing the mind to settle into joyous acceptance of whatever is happening.
If you entertain a feeling of insufficiency, everything becomes insufficient. Nothing is acceptable save joyous acceptance. Only when there is sincerity will the mind settle into joyous acceptance.
Osashizu, May 3, 1890, supp. vol.
To complain that you do not have full use of the body, where no such problem actually exists, is causality. Concerning the things of the world, too, listen and understand without letting any feeling of insufficiency arise in your mind. Settle the truth of joyous acceptance within.
Osashizu, June 3, 1890
Satisfaction broadens the way you live; dissatisfaction causes restriction here and limitation there.
Osashizu, July 14, 1900
