Sahasrara or Crown Chakra
Sahasrara chakra is the chief of all the six chakras namely, Muladhara, Svadhisthana, Manipura, Anahata, Vishuddha, and Ajna. This corresponds to the brain in the physical body. Here the yogi gets the highest state of consciousness and becomes the knower of everything. He is the full-blown Jnani.
Sahasrara, as the name itself, implies that it contains a thousand petals. Hence, there are one thousand yoga Nadis emanates from here. There are one thousand vibrations made by these subtle Nadis. The 50 Sanskrit letters corresponding to the vibrations of subtle channels are repeated for all the Nadis. But some authors describe that the Nadis present in this energy center does not produce any vibration. The position of this Sahasrara energy center is situated above the six chakras and has connections with all of it.
The aspirant can attain the state of Samadhi through this crown chakra. The cosmic energy to the Yogi flows through this energy center. This center is so powerful as when the aspirant duly concentrates in it, that he can see the bright radiance of its presence. This can be seen only when the yogi has attained the required potential in this Sahasrara energy center through meditation. In the book “Why Kundalini Meditation So Special?” I have explained the nature of man doing kundalini meditation and the right way to practice to attain the plausible energy in a short time.
This significant Sahasrara chakra is about knowing and storing the information that is acquired through meditation. The cosmic wisdom passes through this crown and thus the aspirant becomes a full-blown Jnani as I said before. The spiritual energy acquired in this state are also passed to the lower energy centers.
This is characterized by the experience of the within self in the external manifestation of space and time. This energy center is in the brain which is of 13 billion interconnected nerve cells. The bodily functions are being controlled from here. The mind exists here within the plane where you acquire and process the knowledge through the intuition.
Sahasrara Chakra Meditation
The three different states of mind excluding the beta state are attained through Sahasrara chakra in the meditation. These states of mind are classified according to the mental frequencies that are produced in the brain. Mostly the wakeful state of the yogi is having the mental frequency of alpha waves where the mind is in peaceful and calm condition. This is shown by the significant increase in the alpha wave production by the yogis initially when he enters into the meditative state followed by the theta and the delta state. In the final state of the mind, the consciousness gets expanded as the mind frequency is very much low and becomes more perceptible to the divinity which is not possible in the ordinary state of the mind.
In this state, the aspirant will able to know the self. He can see the absolute unity in everything that he is not different from the external cosmic world. This is called as the Sahasrara which means infinity, where the thousand is also depicted as the infinity in the ancient India. This can be also stated as the consciousness of the yogi gets evolved to an infinite state. Here the experiencer, experienced, and experience seems nothing indifference as all are one and the same which can be attained through the Sahasrara chakra.
