There are so many different ways to meditate but one of my favorites (which I will talk about more later, as to why I feel so strongly connected to it) is Om mani padme hum.
Here is one description of this mantra by HH Dalai Lama:
"It is very good to recite the mantra Om mani padme hum, but while you are doing it, you should be thinking on its meaning, for the meaning of the six syllables is great and vast... The first, Om [...] symbolizes the practitioner's impure body, speech, and mind; it also symbolizes the pure exalted body, speech, and mind of a Buddha[...]""The path of the middle way is indicated by the next four syllables. Mani, meaning jewel, symbolizes the factors of method: (the) altruistic intention to become enlightened, compassion, and love.[...]""The two syllables, padme, meaning lotus, symbolize wisdom[...]""Purity must be achieved by an indivisible unity of method and wisdom, symbolized by the final syllable hum, which indicates indivisibility[...]""Thus the six syllables, om mani padme hum, mean that in dependence on the practice of a path which is an indivisible union of method and wisdom, you can transform your impure body, speech, and mind into the pure exalted body, speech, and mind of a Buddha[...]"
—H.H. Tenzin Gyatso, 14th Dalai Lama, "On the meaning of: OM MANI PADME HUM"
