Avalokiteśvara's (Guan Yin's) spirit of boundless compassion and benevolence to promote Buddhist teachings.
Maitrī (Sanskrit; Pali: mettā) means benevolence, loving-kindness, friendliness, amity. Let her thoughts of boundless loving kindness pervade the whole world.
I suppose thats a mantra in buddhism. I was once a follower of Nichiren Shōshū another sect of buddhism. I was told to recite and chant mantra "nam myoho renge kyo" facing the gohonzon, every day. Some buddhist consider this sect as fake. I have no comments. But there was once i encountered an unforgettable experience while i was performing my nite incamp during NS days. Anyway i no longer a follower of this faith.
As for Islam, we are to recite the following in Arabic everyday. I will post in English translation:
"I seek refuge in Allah from satan the accursed" followed by
"In the name Allah, most merciful most compassionate".
Latter mantra quite similar to buddhism. So everything fm Heaven to earth, all belong to Allah. So we ask permission from Allah. When i do my trekking in the jungle, i dont ask permission fm atok, nenek, bunian or jinn. I just recite the above ( 2 points) and the rest leave it to the Creator.
