Surangama sutra (help with mantra)

[Saoshun]

Can someone pounce for me how it should be done with this dharani?

If there are people who cannotput an end to their habits
from the past, you should teach them to single-mindedly recite
my ‘light atop the Buddha’s summit’ unsurpassed spiritual
mantra, mwo he sa dan dwo bwo da la

[DGA]

Here's an audio version of the long dharani. That should help you get a handle on how the Pinyin is pronounced.
