Mūlādhāra (Sanskrit: मूलाधार; IAST: mūlādhāra) is one of the seven primary chakras described in Hindu tantric tradition. The name is commonly translated as "root of existence", being derived from mūla, meaning root, and dhāra, meaning flux or support. It is generally referred to in English as the root chakra.
Within the system of chakras enumerated in tantric texts, Mūlādhāra occupies the foundational position among the seven principal energy centres of the subtle body. As the base of this system, it is treated in tradition as the support upon which the other chakras rest.
Mūlādhāra is symbolised by a lotus with four petals. The associated colour, as represented in traditional iconography, is pink or red. These visual elements form part of the meditative and symbolic imagery used in tantric practice and in textual descriptions of the subtle body.
