The above characteristic feature is observed due to the presence of moisture or water content present in between the layers of mica which tries to escape during heating process and hence gives various characteristic features.

Hence there are total of 16 varieties of Mica i.e. each variety of Mica based on structure has 4 colored type. Out of these Krishna Vajra Abraka is considered as the best variety.

Abraka purification

Abraka shodhana
Before Abraka used for therapeutic use, it should be subjected to purification process (shodhana).

The Abraka layers should be taken and heated till red hot over fire source by holding them with tongs. Then it is immediately dipped in either cow’s urine, gruel (Kanji), decoction of triphala  or milk.

If milk is used for purification process it is considered special or best. The process is repeated for 7 times. This procedure is called Nirvapa.

The purpose of shodhana for abraka is to remove any physical impurity like sand particles which may be collected when extracting from earth.

After the procedure of shodhana, the abraka becomes soft and brittle which is needed for the next procedure called ‘Dhanyabraka’ nirmana.



Dhanyabraka nirmana:
The powdered rough pieces of Abraka is further cut or powdered into small pieces as far as possible. Then the Abraka is taken in a jute bag which contains one fourth quantity of whole rice grain (along with husk) and tied into a bolus form (pottali). This bolus is dipped into a big vessel containing ‘kanji’ (gruel) and kept for 3 days.

After 3 days the bolus is loosened a bit and the jute bag is rubbed vigorously using foot. Care should be taken to protect foot. Again the bolus is dipped in kanji. After an hour, again the bolus is rubbed with foot.

The procedure is repeated a couple of times. Due to the sharp pointed part of the husk and rice grain, the Abraka is pierced and turns to smaller particle. Later the abaraka particles are filtered from the kanji.

In the textbook of Ananda Kanda, another method is explained for Dhanyabraka nirmana. Krishnabraka (black variety of abraka) is taken in an earthen pot and heated very well. Later the Abraka layer is dipped in arka juice (Calotropis gigantia), gruel, cows urine, triphala decoction for 3 times each.
The purpose of this procedure is to soften the Abraka, separate the layers and make it into small particle form so that it can be used for ‘Bhasmikarana’ (powder) form.

Abraka ash

Abraka bhasma:
Chakrika nirmana (preparing round, flat pieces) of Abraka is the initial procedure.

Dhanyabraka is taken in mortar and pestle and mixed with Kasamarda swarasa (juice of Cassia occidentalis) and trituration is done.
Once trituration is completed, abraka chakrika (flat pieces) are prepared and kept in sharava yantra (flat earthen plate) and subjected to ‘gaja puta’. (high quantum of heat).
After cooling, the abraka chakrika are removed and again triturated using Kasamarda swarasa.
The entire procedure is repeated for 10 times. After the 10th time, abraka bhasma is obtained after grinding the abraka chakrika in loha khalva yantra.

Similar methods for the preparation of Abraka bhasma have been mentioned in various texts related to Rasashastra, where the bhavana dravya has been changed.
These are-
• Dhanyabhraka is triturated with Musta swarasa (juice of Cyprus rotundus) to form cakes, which is given Gajaputa of heat. This process is repeated ten times, to get Abhraka Bhasma.
• Dhanyabhraka is triturated with Tanduliya swarasa / Apamarga (juice of Achyranthus aspera) and cakes are given 10 gajaputa of heat.
• Dhanyabhraka is mixed with equal part of jaggery and given Bhavana with Eranda patra swarasa (juice of castor leaves), cakes are prepared, wrapped in Vata patras (leaves of Banyan tree), and this is subjected to three Gajaputa.

To prepare good quality of Baraka bhasma which is used for therapeutic purpose, then abraka should be subjected to 10-100 gaja puta and for Rasayana benefit it is subjected for 100-1000 gaja puta.

Special procedures on abraka

Abraka amritikarana:
The process by which the abraka bhasma attains the property of amrita is called as ‘amritikarana’.

10 parts of Abraka bhasma, 16 parts of triphala kashaya and 8 parts of ghee is taken in a pan together and heated over medium fire till complete the water content is lost. Once the mixture is completely dry, the pan is closed and Abraka is subjected for high heat for some time. After the pan cools, black colored Abraka bhasma is obtained. Then the bhasma is subjected for trituration with decoction of Manjishta moola (Rubia cordifolia root). Later Abraka chakrika is prepared and subjected to gaja puta. The entire procedure is repeated for 4-5 times till the Abraka bhasma lose its shiny nature completely.

Abraka bhasma lakshana:
Properly prepared Abraka bhasma will not be having any luster or shining. It will be red in color, fine powder in nature and soft to touch.
