Definition - What does Streem mean?
Streem is a bija mantra, or single-syllable sound, that increases the inner feminine energy (shakti) and provides the power of the feminine divine. Like the treem mantra, it is associated with the Hindu goddess, Tara. Tara is a form of Durga who represents inner knowledge and is a protective deity. Bija ("seed") mantras typically have no literal meaning but provide a connection to certain energies or spiritual principles, thereby accelerating spiritual, physical and emotional growth.
In yoga practice, bija mantras may be chanted while performing poses or during meditation in order to focus one's concentration on a single purpose and/or to calm the mind.
Yogapedia explains Streem
Chanting streem is believed to enhance poetic and artistic skills, as well as promote powers of debate, argument and the law. Streem is known as a shanti bija, or seed sound of peace and, therefore, carries the energy of pure being. As divine feminine energy, streem is associated with protection, guidance, nourishing qualities and the power of birth. Streem's sound qualities are similar to shreem, but stronger and more stabilizing.
Bija mantras can be chanted alone or as an element in a longer mantra. Although some mantras may be translated, their meanings are less important than their sound vibrations, which provide the real benefit.
