Another popular form of meditation is to repeat a mantra and focus on its sound, or its sound in conjunction with a visual image, while practicing meditation. Your root guru will provide you with a personal mantra for you to use. If you do not have access to a root guru, then the best general mantra for practice is

OM mani padme hum

Repeat this mantra, or your personal mantra, for the full period of your meditation session. Do not merely “parrot” a mantra when you are repeating it. Focus your full attention on the mantra you are using until all other thoughts are excluded from your mind.
