Mala Praying Beads:
A Mala is a set of beads used for counting "mantras" which are the expression of a Buddha-aspect on the level of sound. The number of mantras gets counted to ensure certain meditation results will occur
In Tibetan Buddhism, traditionally malas of 108 beads are used. Doing one 108-bead mala counts as 100 mantra recitations; the extra repetitions are done to amend any mistakes. The materials used to make the beads can be different according to the purpose of the mantras beening used. These beads can be made from Bodhi seeds, Rudraksha seeds, lotus seeds( called 'Moon and Stars' by Tibetan) , sandalwood, abelia, gold, silver, copper, iron, crystal, coral, ivory, amber, coloured glaze, turquoise, giant clam, pearls and so forth, and even bones of a holy monk or revered lama..

Choosing a Mala:
A mala of 108 beads is used for general purposes by most practicing Tibetan Buddhists. A variation of the standard 108-bead mala is the wrist mala of 27 beads—four circuits total 108 mantra repetitions.
"The sacred number of 108 predates Buddhism, being the classical number of the Hindu names assigned to a deity or god. As a multiple of 12 and 9, it represents the nine planets in the 12 zodiac houses. As a multiple of 27 and 4, it also represents the four quarters of the moon in each of the 27 lunar mansions or constellations.
The 108 beads also ensure that at least a hundred mantra recitations have been completed in a full rosary turning."
Beads of bodhi seed generally are considered auspicious for any practice or mantra, and red sandalwood or lotus seeds also are widely recommended for universal use .
