This is a term appearing in the Scriptures. It is of crucial importance for the mind and the innermost heart to become clear and pure if the Joyous Life is to be realized. This is indicated by the following often-quoted verses from the Ofudesaki: Tsukihi will teach about every matter to all humankind equally, and the world will be filled with joy.

If only human beings throughout the world have purified their minds and lead lives joyously. . .

When the mind of Tsukihi is truly spirited, so will be all human beings.

When the minds of all the world are spirited, Tsukihi and human beings will be one in mind.

Ofudesaki VII:108-111

The thoughts that arise in the human mind in the course of daily life, however, tend to be "only of dust" (Ofudesaki XVII:68-70) and thus make the mind cloudy and murky.

Greed is fathomless like muddy water.
When your mind is completely purified,
Then comes paradise.

Mikagura-uta X:4

Unaware of the truth (referring to the intention of God the Parent and the truth of the world), we repeatedly fall into errors, which invite misfortune (Ofudesaki XIII:41-49). Feeling regret over this condition, God the Parent desires to help us in all respects possible--whether at the level of our daily lives or at the level of working with the mind. God the Parent goes to great lengths to help us attain salvation. These efforts of God the Parent are sometimes referred to as "returns" (kayashi) (Ofudesaki V:46-49, 50-55).

When God in Truth begins to work, the minds of all in the world will be purified.

What are your thoughts concerning My workings? I shall give returns when I accept your minds.

Ofudesaki V:49-50

Whether you speak good or think evil, I shall give returns at once as you deserve.

If you begin to see this, My purification will reach any and everyone in the whole world.

Ofudesaki V:54-55

The phrase "If you begin to see this" refers both to the manifestation of what is talked about above and to our ability to see or understand it.

The "returns," as explained in some detail in the Ofudesaki's verses VI:80-123, may take the form of illnesses or other troubles (Ofudesaki VI:91-93, 115-116, VIII:58), or they may come as the blessing of salvation (VI:101-102, 106, 109). Yet, we may not be able to "see" readily (if we lack knowledge) that illnesses and other troubles represent some of the ways God the Parent works to help us or that salvation really comes from God the Parent's workings. Indeed, one may find it hard to accept that illnesses and other troubles are expressions of God's guidance. Again, when one's physical condition improves after an administration of the Sazuke, the Divine Grant, one may not readily believe that the Sazuke has actually called forth that blessing. These difficulties stem from a lack of knowledge and understanding with regard to the truth about the workings of God the Parent. Thus, those who cannot "see" would do well to develop the ability to "see" by getting help from those who can "see" (those with knowledge). Says the Ofudesaki:

Until now, no matter what I had told you, you have not been able to see anything.

Even until now, all things have already appeared, but you have not known their true origin.

Thunder, earthquakes, great winds, and floods: these are from the regret and anger of Tsukihi.

Because no one has ever understood this matter, this time Tsukihi will tell you about them beforehand.

Ofudesaki VIII:56-59

When the mind becomes clear and pure--thereby allowing for an understanding of the teachings and spiritual growth--anyone will be able to see the workings of God the Parent. This, in turn, is said to enable the mind to become high-spirited (Ofudesaki V:77, VI:14-15, XII:44-45).

When the mind is made pure and open to reason, the truth will be seen of its own accord.

Ofudesaki V:77
