This poem takes the form of a koan, using a recursive procedure as a meditation on consciousness. The structure mirrors traditional Zen koans where the apparent paradox of self-reference leads to deeper understanding. The ALGOL keywords and operations themselves become part of the poetic flow, with 'LOC' and 'SKIP' suggesting temporary states of mind.
Written in ALGOL 68, the poem implements a recursive procedure that: 1. Defines a MODE for mind as a REF to a REAL value 2. Uses a base case where consciousness fades to NIL 3. Implements recursive self-calls that build up and then unwind 4. Uses ALGOL 68's CO keyword for comments 5. Employs 'SKIP' as a meditative pause in the recursion The recursive pattern reflects both technical accuracy and meditative depth.
The poem explores how consciousness reflects upon itself, much like ripples in a pond. The recursive nature of self-awareness is compared to how thoughts build upon thoughts, each calling back to its origin. The transformation through recursive contemplation suggests that deep introspection leads to understanding. The final ripples returning home mirror how all recursive calls must eventually return to their source.
