Seeing is a fundamental aspect of life. Even with the blind people, they continue to ‘see’ in their inner space. The truth is, whether we are blind or have the physical eyes, we continue to see through our inner eyes. Seeing is life, life is nothing but seeing. However, seeing with the 3rd eye (Agna chakra) is conscious seeing.
The science of opening the 3rd eye is a unique contribution of the Vedic tradition. If you see all the Hindu gods and goddesses, you will see them with 3 eyes. It means that only if your 3rd eye is awakened, you can become a God. For Hindus, the possibility of opening the 3rd eye exists because they keep the bindi or kum kum (processed turmeric powder) on the 3rd eye, which awakens it.
