昆达里尼（梵文：कुण्डलिनी，kuṇḍalinī，坦米尔语 : வாலை，泰语: กุณฺฑลินี，英语：Kundalini），又译为军荼利、灵量、拙火，梵文原义是卷曲的意思，印度瑜伽认为，它是一种有形的生命力，是性力的来源，它蜷曲在人类的脊椎骨尾端的位置。传统印度常以女神，或是沉睡的蛇来作为它的象征。类似于中医与道家所说的精或先天的炁，印度瑜伽修行者认为，通过修练瑜伽，将可以唤醒沈睡在身体中的昆达里尼，使它通过中脉，最终到达梵我合一的境界。

Kundalini (Sanskrit kuṇḍalinī, कुण्डलिनी,  pronunciation , "coiled one"), in yogic theory, is a primal energy, or shakti, located at the base of the spine. Different spiritual traditions teach methods of "awakening" kundalini for the purpose of reaching spiritual enlightenment. Kundalini is described as lying "coiled" at the base of the spine, represented as either a goddess or sleeping serpent waiting to be awakened. In modern commentaries, Kundalini has been called an unconscious, instinctive or libidinal force, or "mother energy or intelligence of complete maturation".
