Take asafoetida, the five salts, the three alkalies, *Rumex vesicarius*, sal-ammoniac, the ripe fruit of the croton plant, *jalamukhi* (*Anthericum tuberosum*), *rudanti* (*Asclepias rosea*), the root of *Plumbago zeylanica*, and the milky juice of *Euphorbia antiquorum* and *Calotropis gigantea*—rub all these together and make them into a ball Place inside it the noble and luck-yielding gems Wrap the ball with the leaves of *Betula bhojpattra* and tie them with thread, and enclose the ball again in a piece of cloth, and suspend it in a dola yantra filled with the acids and sour gruel, and apply strong heat for three days and nights—the liquid principle of the gems is thus collected. 64-69
