Hexagram 31: 咸
xián — reciprocity
Judgment
Influence. Success. Perseverance furthers. To take a maiden to wife brings good fortune. Bell didn't force the signal through—he found the frequency where natural resonance occurs. The system works because both sides are designed for mutual reception.

Lake on the mountain: the superior man encourages people to approach by readiness to receive them. Bell's receiver had to be as carefully designed as the transmitter. One-way broadcast isn't influence—it's noise. True influence requires receptivity on both sides.

The First Telephone Call
Alexander Graham Bell (1876)
'Mr. Watson, come here, I want to see you.' The first words transmitted by telephone were a request born of spilled battery acid—Bell needed help. But beneath the mundane emergency: proof that influence could travel as electrical signal through wire, that voice could stimulate a diaphragm that created current that stimulated another diaphragm that recreated voice. The receiving device responding to the transmitting device, both systems attuned to the same frequency. The classical text describes influence (Hsien) as mutual attraction—the hexagram represents courtship, the youngest son and youngest daughter drawn together. Bell's telephone is this principle made hardware: two systems in sympathetic resonance, influence transmitted not through physical presence but through aligned receptivity. The sender takes the lower position (generates signal), the receiver responds joyously (reproduces it). Connection requires both.
Historical Context
