This Tibetan trengwa exemplifies the simple but traditional structure of prayer beads used by Tibetan Buddhists. The 108 beads can be used universally for all types of practices but are said to be especially suitable for practices of increase or expansion. The 108 beads are usually divided into 4 groups of 27 by 3 additional separator beads, typically of a different material and a bead that connects the two ends of a strand, usually a little larger and topped by a stupa-shaped attachment, called a guru bead. The symbolism of the guru bead varies in different traditions but generally signifies the ultimate truth, or Dharmakaya, understood as a formless dimension of the Buddha’s enlightened body.
