Shrivatsa Yoga is a connection between the powerful endless knot symbol and traditional Yoga:
Shrivatsa or "Endless Knot" is a symmetrical symbol where knots tie into themselves, crossing and interlocking each other. It is a symbol for eternity, compassion, wisdom and harmony. It is also one of the eight auspicious symbols in Tibetan Buddhism, representing the interconnection of all beings, without beginning or ending. The intertwining of the lines also represents how all events, past, present and future are bound by never ending cycle of cause and effect.
Besides Tibetan Buddhism, the endless knot has been independently used in many other cultures, for example in the Celtic tradition. The Celts were a diverse group of tribal societies in Iron Age Europe. They used the endless knot symbol in their shamanic practices as a symbol of Truth and as a protection against demonic forces. It was also used as an amulet of personal protection and to guard windows and doors.
In meditation, the visualization of the shrivatsa symbol helps to open the heart chakra, allowing cosmic prana to get in to heal us, protect us and guide us.
Although Yoga has its origins in India, it has long ago overcome the Indian tradition and has become an international phenomenon. New forms of Yoga are arising and many modern yoga practitioners around the world have contributed to the development of the great Yoga system.
The symbol of Shrivatsa symbolizes the unification of the "old" Yoga school and the "new" Yoga school. It also links the yogic practices with other spiritual practices like taichi and qigong. In Shrivatsa Yoga, the practice is "endless", without limitations. Since the symbol of Shrivatsa Yoga is also a sacred symbol used in connection with the spirit world, it creates a bridge between Yoga and Shamanic Healing.
From my own experience, shamans who use Yoga as a tool for self-realization and self-study, are the most integrated and unique healers of all.
