The six centers combine to make the seventh center: Sahasrara

So, this last center, the Sahastrara, is contained in the limbic area of the brain. Our head is like a coconut. The coconut has the hair, and then a hard nut and then a black covering and inside is white shell of coconut and inside is the space, the water. In the same way, our brain is made. That's why coconut is called as Shreephala. Is the fruit of the power that is Shree. Shree power is the right side power and the left side power is the Lalita power. So, we have two Chakras - left side, here, is the Lalita and right side, here, is the Shree Chakra. These two Chakras are working out the right side Mahasaraswati's power and left side Mahakali's powers.

Now, the central power is the Kundalini. That has to rise and penetrate through different Chakras, enter into the limbic area and enlighten the seven Pithas - seats of these seven Chakras. So, it penetrates through six Chakras, enters into the limbic area, enlightens all the seven Pithas in the brain, which are placed along the mid-line of the limbic area. So, we start it from the back, is placed here, at the back, is the Mooladhara Chakra. Around it is the Swadishthana, then is the Nabhi, then the Heart, then the Vishuddhi and then the Agnya. So, all these six centers are combining to make the seventh center. This is a very important point, which we should know. Now, the Shree Chakra is the right side working and the Lalita Chakra is the left side working. So, when the Kundalini doesn't rise then we do with our right side our physical and mental activities. So our brain is doing right side activity and that's why our brain is like Shreephala.

Sahastrara is actually is the assemblage of these six Chakras and is a hollow space, on the sides of it there are one thousand Nadis. And when the light penetrates into the limbic area, then the enlightenment of these Nadis take place and you can see them as flames, very gentle flames burning and these flames have all the seven colors that you see in the
​VIBGYOR (Violet Indigo, Blue, Green, Yellow, Orange, Red]
. But the last one, ultimately becomes again integrated and it is a crystal clear flame. All these seven lights ultimately become crystal clear.

So, you have Sahastrara with one thousand petals, as they called it, but if you cut the brain in a transverse section or horizontal section, you will be able to see that all these nerves are built like this along the limbic area, all of them are like a petal, and if you cut it like this, you will find that there are many nerves in every bundle of nerves. So, when it is enlightened, you can see Sahastrara as a burning bundle of flames.
