"Grok" is a Martian word introduced by Robert A. Heinlein meaning to understand something so completely that you become one with it. In Stranger in a Strange Land, grokking transcends intellectual comprehension—it represents drinking in knowledge with your entire being until the observer and observed merge. Mike Smith teaches this concept to humans, explaining that Martians grok water's preciousness because of its scarcity on Mars, creating profound respect and spiritual connection.

Stranger in a Strange Land argues that language fundamentally shapes how we perceive reality and that human sexuality represents humanity's greatest gift. Robert A.

The novel ultimately advocates for spiritual transformation through deeper understanding (grokking), communal living, and embracing human sexuality as a path to profound connection and consciousness expansion.

Water-sharing in Stranger in a Strange Land is a sacred Martian ritual where individuals drink from the same glass, creating "water brothers"—a bond deeper than any human relationship. Because water is scarce on Mars, sharing it represents ultimate trust and connection. When nurse Jill Boardman innocently offers Mike Smith water at the hospital, she unknowingly forms this profound bond. Mike later teaches that water-sharing parallels human kissing and sexual intimacy as ways of "growing closer."

Stranger in a Strange Land critiques organized religion through contrasting the corrupt Fosterite Church—which commercializes sin—with Mike Smith's Church of All Worlds, which combines Martian philosophy with human sexuality and esoteric practices. Robert A. Heinlein examines how institutions manipulate spirituality for power while suggesting authentic spiritual growth comes from communal living, shared consciousness through Martian language study, and embracing sexuality as sacred.
