Although you’ll find quite a lot of Chakra Massage or Chakra Balancing Massage being offered nowadays, it’s not really a traditional massage modality within Ayurveda, but rather derived from Tantric practices.
Nevertheless, it’s believed that they can be influenced or manipulated indirectly, for instance, through massage of Marma point locations. As such, the Chakras can receive a “massage,” and can be “balanced.”
As the Chakras are thought to be located along the spine, that is, along the Sushumna Nadi Prana Energy Channel, it’s common that massage work is often concentrated around the spinal column, by applying strokes, deep tissue work and acupressure in the area.
Other ways to “access” or “massage” the Chakras are, for instance, through Foot Reflexology acupoints or — something completely different — through sound (vibrations) by using so-called Singing Bowls. Direct energy work is an option also; think of hand-healing techniques, such as Reiki.
At any rate, the main goal of Chakra Massage or Chakra manipulation is to open or unblock the Chakras i.e. stimulate their proper functioning, which is thought to promote the free flow, proper distribution and functional transformation of Prana Life Energy in the body for health benefits.
