The Metta Meditation or The Loving Kindness Prayer as it  is also know is meditaiton with the intentioin of fostering kindness and compassion for ourselves and for others. Typically seen as 5 lines with some variations it goes like this:
May all beings  be peaceful, (howlite)
May all  beings be happy, (crazy lace agate)
May all beings be safe, (tourmaline)
May all beings be awaken to the light of their true nature, and (labradorite)
May all  beings be free (free from suffering) (amazonite)
Then you repeat it but switch 'all beings' to 'me'. Then repeat it again and replace 'me' with the name of  someone who you may have ill feelings for.  It is incredibly powerful to offer loving kindness to  someone who may not deserve it...it frees you from the attachment of anger or resentment or  whatever ill feelings keeps you attached to that person. This mala may be one of the most benficial malas I have made.  All beads are 6mm and the guru is clear quartz for healing and to amplify the effect.  White tassel and white cord  for a purified influence.
