★ “Deep thinking is dialogue with a wise other self.” Tasaka says everyone has within them a wise other self. What separates our abilities and lives is whether we notice it and know how to converse with it.
★ The book presents five psychological techniques and 32 essays: how to let the wise other self begin to whisper through writing, how to let intuition flash, how to break unconscious self-limitation, and how to escape superstitions that block talent. It offers techniques, not abstract theory.
★ One chapter is called “The Practice of Dying Tomorrow.” Tasaka says deep thinking begins when we realize we may die tomorrow. This is not negative; it makes each moment clearer.
★ Writing lets the wise other self whisper. Reading and writing are not information processing but “descending the stairway of thought.” For readers seeking deeper judgment and creativity beyond logical thinking.

Your inner self holds a wisdom beyond imagination.

The author says deep thinking is “dialogue with a wise other self,” and presents five psychological techniques and 32 essays never told before. This is a book that lets wisdom beyond logical thinking emerge.

● The “wise other self” within everyone
● The “unconscious self-limitation” that blocks our abilities
● The ultimate technique for letting intuition flash

“In truth, within each of us, deep in our hearts, there exists a ‘wise other self’ with wisdom beyond imagination. What separates our abilities and our lives is whether we notice the existence of that ‘wise other self,’ and whether we know how to converse with it.” (From Part 1: The Wise Other Self)
