58 · The Joyous (DUÌ)
Two joined lakes suggest delight that can be shared. The Image turns this into friends studying and discussing together. The Tuan joins an inward firm center to an outward gentle manner. Six lines distinguish harmony and trust from flattery, then ask when to set a boundary and whom to trust. The final invitation toward joy remains unresolved rather than automatically good or bad.

The judgment
The Joyous: passage. Steadfastness is beneficial.
Joy can open a way, but delight alone is not a guide. Classical commentary warns that pleasing others can turn into flattery. The favorable condition is integrity within the pleasure.
