Chakra
cakraThe body's energy centers, usually pictured today as seven colored wheels along the spine.
The hatha texts speak of centers, lotuses, and knots that practice pierces as energy rises:
When the sleeping Kuṇḍalinî awakens by favour of a guru, then all the lotuses (in the six chakras or centres) and all the knots are pierced through.
The original Sanskrit
suptā guru-prasādena yadā jāgarti kuṇḍalī / tadā sarvāṇi padmāni bhidyante granthayo'pi ca
