A "2 mm rudraksha mala" refers to a prayer or meditation mala made of rudraksha beads that have a diameter of 2 millimeters.

Rudraksha beads are seeds from the Rudraksha tree, known for their spiritual significance in Hinduism. These beads are commonly used for meditation, prayer, and spiritual practices.

A mala is a string of beads used for counting recitations of mantras or prayers. It typically consists of 108 beads, although variations with different numbers exist. The beads are strung together on a thread or string, with a larger bead called the "guru bead" or "meru" serving as a starting and ending point for the counting process.

In the case of a 2 mm rudraksha mala, the beads used are 2 millimeters in diameter. This indicates that the beads are slightly larger than the 1 mm rudraksha mala mentioned earlier. The size of the beads can affect the overall appearance and feel of the mala. Smaller beads often result in a more delicate and lightweight mala, while larger beads can create a more substantial and noticeable presence.

Wearing or using a rudraksha mala during meditation or prayer is believed to enhance focus, promote spiritual well-being, and facilitate a deeper connection with the divine. The size of the beads is a matter of personal preference, and individuals may choose a mala based on their comfort and the desired aesthetic.
