    Notes:
    Equal to Guanyuan Ren-4 for tonifying the Kidneys but has a stronger effect on nourishing qi and yang rather than blood or yin. Both points share the name of Dantian referring to the lower energy centre.

    The lower Dantian or cinnabar field is located in medical texts at 1.3 inches below the navel which would indicate this point but alchemical texts describe this as 1.3 inches behind the navel, i.e. behind Ren-8 (Wang Mu, 2011, Foundations of Internal Alchemy)

    In Thai massage:
    Main acupressure point of the Nantakawat sen lines which run from the navel Shenque Ren-8 to the excretion organs, the anus and urethra (Salguero & Roylance, 2011, Encyclopedia of Thai Massage).

    If gates along the microcosmic orbit are considered in terms of qabalistic sephirot then this point would be equivalent to hod along with Guanyuan Ren-4.
