Third Eye activation occurs as a result of meditation techniques that stimulate the Third Eye Chakra. By sending energy and awareness to the Third Eye, it is stimulated. When you focus awareness and energy via meditation, the brain, and nervous system, and all of your mental functions become relaxed, purified, enlivened, and strengthened. This begins a process of activating your Third Eye, your Ajna chakra.
When your Third Eye is activated, you see into and experience your inner world. You begin an inner journey to develop this newly discovered part of you.
Through an awakened third eye you can see your inner world as clearly as you can see your outer world. You can connect with your higher self, which enables access to the deepest truths, and the hidden powers of your mind and the cosmos.
In Indian philosophy and yogic metaphysics, it is said that Ajna Chakra is the center where you transcend duality—the duality of a personal “I” that is separate from the rest of the world; the illusion of a personality that exists independently from everything else.
A yogi who passes through Vishuddhi, or the throat chakra, to the sixth chakra at the eyebrow center, experiences themselves as beings of light and realizes the interconnectedness of all beings. You become Mukta, which means liberated, freed from the bondage of time-bound consciousness. This is where I-consciousness is absorbed into the super-consciousness in a process called Samadhi in Sanskrit.
