At that time, last year, I thought that it was understood, but lately, only last month, somebody who should be in the know, someone who has participated in development work for quite a long time, came to see me and said that the sufficiency economy was a very good system, and he indicated his understanding that the application of one-fourth of the sufficiency economy means the coverage of a quarter of the area in the country. The meaning of sufficiency economy and only one-fourth of its application did not mean the area of one-fourth, but one-fourth of the extent (degree) of sufficiency.
