taj japah tad artha bhavanam

Yoga Sutras of Patanjali, 1.28

taj = that (OM)
japah = repetition
tad = that (OM)
artha = meaning
bhavanam = reflection

This is an abstract one where the bright colours represent everyday life and the paler background represents the palatable peace you feel when chanting and meditating on OM, it also represents the fact that it is always there too.
