Definition - What does Kleem mean?
Kleem is a one-syllable sound known as a bija mantra and is associated with Kamadeva, the Hindu god of love. In some Hindu traditions, Kamdeva is an incarnation of Lord Krishna. Kleem is chanted for its power of attraction.
Bija mantras usually have no specific meaning but are recited for their spiritual powers or energy to stimulate emotional and spiritual transformation. In yoga, bija mantras may be repeated as part of meditation or during asana practice to focus on a single purpose or to calm the mind. Although kleem can be chanted alone, like other bija mantras, it is often recited as part of a longer mantra.
Yogapedia explains Kleem
Kleem (also spelled klim) is considered a shakti mantra, or one that stimulates the divine feminine energy. In tantric yoga, shakti mantras like kleem are the primary mantras; although, they are used in other types of yoga as well. They transform life force energy and consciousness at the deepest levels. The magnetic energy of kleem draws things to us, but can also hold things in place. It is one of the most widely used of the bija mantras.
In the traditional Indian medical practice of ayurveda, kleem promotes water (kapha), making it a beneficial mantra for the skin and the reproductive system, as well as the brain, immune system and nervous system.
