When the swastika had a different meaning.
The word swastika is derived from the Sanskrit word svastika (in Devanagari स्वस्तिक), meaning any lucky or auspicious object, and in particular a mark made on persons and things to denote good luck. It is composed of su- meaning "good, well" and asti "to be" svasti thus means "well-being." The suffix -ka either forms a diminutive or intensifies the verbal meaning, and svastika might thus be translated literally as "that which is associated with well-being," corresponding to "lucky charm" or "thing that is auspicious." The word in this sense is first used in the Harivamsa. As noted by Monier-Williams in his Sanskrit-English dictionary, according to Alexander Cunningham, its shape represents a monogram formed by interlacing of the letters of the auspicious words su-astí (svasti) written in Ashokan characters.Photo via Black and WTF.
