The term “Shat-Chakras” refers only to the chief six Chakras, viz., Muladhara, Svadhishthana, Manipura, Anahata, Vishuddha and Ajna. Above all these we have Sahasrara Chakra. This is the chief of all the Chakras. All the Chakras have their intimate connection with this centre. Hence this is not included as one among the Shat-Chakras. This is situated above all the Chakras.
Lalana Chakra:
Lalana Chakra is situated at the space just above Ajna and below Sahasrara Chakra. Twelve Yoga Nadis emanate from this centre. The vibrations that are made by the 12 Nadis are represented by the Sanskrit letters: (Ha, Sa, Ksha, Ma, La, Va, Ra, Ya, Ha, Sa, Kha and Phrem). It has OM as its Bija. At this centre the Yogi concentrates on the form of his Guru and obtains all knowledge. This has control over the 12 pairs of nerves that proceed from the brain to the different sense-organs.
The Mysterious Kundalini
Manastvam Vyoma tvam Marudasi Marutsarathirasi,
Tvamapastvam Bhumistvayi parinatayam nahi param,
Tvameva Svatmanam parinamayitum visvavapusha
Chidanandakaram haramahishi-bhavena bibhrushe.
“O Devi! Thou art the mind, the sky, the air, the fire, the water, and the earth. Nothing is outside Thee on Thy transformation. Thou hast become Siva’s consecrated queen to alter Thy own blissful conscious Form in the shape of the world”.
