H. P. Blavatsky says:
Few world-symbols are more pregnant with real occult meaning than the Swastika. It is symbolized by the figure 6; for, like that figure, it points in its concrete imagery, as the ideograph of the number does, to the Zenith and the Nadir, to North, South, West, and East; one finds the unit everywhere, and that unit reflected in all and every unit. It is the emblem of the activity of Fohat, of the continual revolution of the ‘wheels’, and of the Four Elements, the ‘Sacred Four’, in their mystical, and not alone in their cosmic meaning; further, its four arms, bent at right angles, are intimately related, as shown elsewhere, to the Pythagorean and Hermetic scales. One initiated into the mysteries of the meaning of the Swastika, say the Commentaries, ‘can trace on it, with mathematical precision, the evolution of Kosmos and the whole period of Sandhya’.
The swastika is, par excellence, the symbol of cosmic evolution. It is an image represented in many temples in India, Tibet, China and other countries with Hindu and Buddhist influence (and indeed the very symbol of esoteric Buddhism). Moreover, it is present in the traditions of the Nordic peoples and in pre-colonial Americas.
Being a universal symbol, the swastika cross is also present in the symbol of the theosophical movement.
The representations of Buddha with the Swastika cross on his chest, being called the ‘Seal of the Heart’, are well-known. The swastika is also present in many ancient Christian relics. About its universality, HPB states:
[The] ansated Egyptian cross, or tau, the Jaina cross, or Swastika, and the Christian cross have all the same meaning.
Despite these facts, or maybe because of them, Christian missionaries tried to classify the swastika as “diabolical”, thus trying to destroy one of the oldest sacred symbols, which is also at the origin of “their” own Christian cross. Yet to honestly recognize the evolution of the cross as a symbol would be like accepting that Christianity illegitimately adopted religious images belonging to much earlier traditions.
There is a right-handed swastika and a left-handed one, each revolving in opposite directions. The right-handed is called “swastika” while the left-handed is sometimes called “swavastika.” If clockwise movement signifies natural evolution and life, and counter-clockwise indicates regression or death and is an inversion of nature, the Nazi “swastika” would represent this inversion. The symbol was chosen possibly because it was thought to be of Nordic origin, and it was used as a caricature of the Christian Cross. The swastika can clearly symbolize good or evil, thus echoing its inherent double nature. But many of its uses in past ages indicate both directions in contexts that were purely spiritual in nature and which strongly suggest another interpretation. The right arm points to heaven, the left to earth, and this varies depending upon the perspective. If the symbol faces away from one, the hooks point counter-clockwise. If the symbol faces one, the hooks point clockwise. These two perspectives symbolize the microcosmic and the macrocosmic. Man, the perceiver, embodies one while reaching out toward the other.
Being a double symbol, the swastika also represents male and female combined in the hermaphrodite. Thus, it is found carved upon the figure of Ardanari in South India, denoting the pre-sexual state of the Third Root Race. In another old Hindu carving, Vishnu is shown as double-sexed, floating on the water which rises in a semicircle and pours through a swastika representing the source of generation. All subsequent evolution takes place spirally from within, like the directional unfolding of the swastika implicit in the “wheel of Dharma,” the sacred law to which the Buddha pointed. The Upanishads teach that in accordance with natural law, it is necessary to turn the wheel from within, to emulate the fohatic force which expands throughout the Cosmos vitalizing every atom and awakening every conscious center.
