The term sauwastika (or sauvastika) is sometimes used to distinguish the left-facing from the right-facing swastika symbol, a meaning which developed in 19th century scholarship.
The left-facing variant is favoured in Bon and Gurung Dharma; it is called yungdrung in Bon and Gurung Yantra in Gurung Dharma. Both the right-facing and left-facing variants are employed in Hinduism and Buddhism however, the left-facing is more commonly used in Buddhism than Hinduism and the right-facing is more commonly used in Hinduism than Buddhism.
In Buddhism the left-facing sauwastika imprinted on the chest, feet, palms of Buddha and also the first of the 65 auspicious symbols on the footprint of the Buddha. In Hinduism the left-facing sauwastika is associated with esoteric tantric practices and often stands for Goddess Kali.
