A mala is a great tool to help enhance your mediations. The use of a mala can help focus your meditation while adding the unique properties of the mala to improve the power of your meditation.
Anatomy of a Mala:
A mala is a string of beads used for prayer. Malas are made on the principle of the sacred number 108, so they will have either 108 beads or a divisible of that number: 54 or 27 beads. They are usually strung on silk thread with knots between each bead to maintain consistent space between each bead. They also have a Guru bead with a tassel hanging from it. The tassel is considered the symbol of a thousand lotus petals.
The amazing thing about meditating with a mala is that it combines Naad yoga (the recitation of sacred sounds), acupressure, gemstone therapy and a deep meditative practice.

Mantras and Malas:
When reciting a mantra with a mala meditation, you recite the entire mantra on each bead (not one bead per word). You can also use affirmations with your mala, repeating the affirmation with each bead. The recitations can be done silently, as a whisper, in song or spoken out loud.
The History of the Mala:
Malas are also known as prayer beads. Using beads for prayer as a meditation tool dates back beyond written history. You can see them used as a tool in almost every spiritual and religious practice. The oldest known form of the prayer bead is the Japa Mala used in Hindu prayer.
In the lineage of Kundalini Yoga, there is a strong history of the use of the mala both from the Kundalini teachings and the Sikh faith. Guru Nanak, whose writings are the foundational text of all Kundalini Mantras is almost always depicted with a mala in his hand or around his neck. Guru Ram Das, the teacher whose healing energy is so often called on in Kundalini meditations was also known to be constantly chanting with his mala, and many of the images of him show him with a mala in hand. Yogi Bhajan carried a mala with him all of the time and seemed to always be reciting his meditations as he taught, met with people, and did all the daily tasks in his life.
