Lalana chakra, sometime known as Talu chakra is located at the root of the palate or the back of the mouth. Once Amrit falls from Bindu it is stored at Lalana chakra ready to be purified by Vishuddha chakra. Kechari mudra is said to direct the flow of Amrit from Lalana chakra to Vishuddha chakra. If Vishuddha chakra is inactive Amrit falls down to Manipura Chakra where it is devoured, and decline happens. Hatha yoga says controlling Amrit prolongs life.
Amrit is first mentioned in the Rig veda: 8.48.3
ápama sómam amritaā abhuma
áganma jyótir ávidama devan
kím nunám asman krnavad áratihḥ
kím u dhurtír amrta martiyasya
“We have drunk soma and become immortal; we
have attained the light, the Gods discovered.
Now what may foeman’s malice do to harm us? What, O Immortal, mortal man’s deception?”
Bindu is a dot at the top back of the head located above Ajna chakra and below Sahasrara chakra. Bindu is the storehouse for Amrit and is thought to prolong life. Bindu is also explained as everything in its unmanifest form, or the microcosm of everything. The macrocosm is the universe around us.
Bindu is the storehouse of all Karmas of man from previous lifetimes, both in Vasanas and memories.
The word Bindu means ‘drop’ or ‘point’ and is more correctly termed Bindu visagara which means ’falling of the drop’. The representation of Bindu is the crescent moon and a drop, which is nectar dripping down to Vishuddhi chakra. Bindu is the ultimate source out of which all things manifest, and then return.
“Bindu is the cause of the creation of word and meaning, now entering and now separating from one another. From that Bindu came ether, air, fire, water, earth and the letters of the alphabet”
The tuft of hair at the back of the head which Brahmins have is called shikha and means flame of fire. Flame stands for the flame of vasanas or hidden karmas form past lives.
In Tantra the symbol of the of Bindu is a crescent moon on a moonlight night. This symbol is rich in meaning indicating the that Bindu is closely related to the kalas, or phases of the moon, is the human body. The background of the night sky also symbolises the infinity of Saharara beyond Bindu. Th symbol of Om also contains the representation of Bindu, a small point above a crescent moon.
It is said that if the secretion is controlled then yogis can live on the nectar alone.
Besides producing nectar Bindu produces poison. It is said that if controlled through Hatha yoga then the poison is controlled.
ORIGIN OF CREATION
Bindu is considered to be the origin of creation or the point where oneness first divides itself to produce individual forms. The word Bindu can be traced back to the Sanskrit root word bind, which means ‘to split’ or ‘divide’
Bindu implies a a point without dimension or dimensionless centre. Some Sanskrit texts define it as chidghana, with its roots in limitless consciousness. Bindu is considered to be the gateway to shoonya, the state of void.
Khechari mudra is the practice of rolling the tongue back to the pharynx to stimulate the flow of Amrit from
Lalana chakra to activate Vishuddhi chakra.
The focus is the third eye at bhrumadhya. Close the eyes and turn them up towards the eyebrow centre with the eyebrows slightly lifted. The tip of the tongue presses gently into the space where the teeth and gums join. Ajna bandha is said to connect Lalana chakra, Vishudhi chakra and the third eye, and aid the accession of prana along shushumna, to unite at the third eye. Ajna bandha will create a space of stillness and focus.
