The Left Angle Cross of the Plane is named for Gate 6 and Gate 36, the same pair that names the Juxtaposition Cross of Conflict, here read inside a different angle family. Human Design reads Gate 6, from Hexagram 6, Conflict, as the friction that both guards and opens intimate and sexual contact, and Gate 36, from Hexagram 36, Darkening of the Light, as the turbulence of an experience that is genuinely new. It belongs to the Left Angle family, read as transpersonal, a direction practitioners describe as answering less to personal choice than to what circumstance hands the individual, which is where the cross reads its name of the plane from.
Its design half is Gate 15 and Gate 10, both in the G, or Identity, centre. Gate 15 is read as a love of humanity broad enough to embrace extremes; elsewhere it pairs with Gate 5 in the channel of Rhythm. Gate 10 is read as conduct that stays true to one's own nature rather than to expectation; it pairs with Gate 20 in the channel of Awakening.
Carrying the same gates as a fixed Juxtaposition cross but inside a transpersonal, Left Angle reading changes what the pattern is understood to serve, an intimacy handed back by circumstance rather than a note simply held. The hexagrams are ancient; the pairing and the angle both belong to the modern system, dated to 1987.
