According to Osho, chakras are the junction points where the subtle body touches the gross body—fixed, universal fields present in all beings. There are seven such centers. They may be active or dormant: nature activates a few, while meditation and yoga can switch on higher chakras. As higher centers awaken, energy naturally withdraws from lower ones.
Chakras are like plug sockets where your invisible self plugs into your body; everyone has seven, and practice can wake the sleepy ones.
