Recitation of Po Jo Po Lo Mi To Hsin Ching, Prajna Paramita Hrdaya Sutra in Sanskrit, or the Heart Sutra (Hsin Ching) in short, is for establishing connections with Guan Yin Bodhisattva, and to obtain wisdom through the mercy and compassion of Guan Yin Bodhisattva. This sutra takes the form of energy in the Asura realm and the Deva realm (known as “Heaven” in English), currency in the underworld, and wisdom in the human realm. Some of its great powers include: disciplining misbehaved children; influencing adults to have a religious belief e.g. Buddhism; communicating with elders who are stubborn; calming emotions; granting wisdom; and alleviating depression. It can also be used for performing the transferring of merits to the deceased.
The full title of each sutra and mantra should be included each time before it is recited. For example, before reciting the content of the Heart Sutra, you should recite its full title: Po Jo Po Lo Mi To Hsin Ching.
For Daily Recitation: Generally 3 or 7 times per day until the end of life. The Heart Sutra can be recited until 10PM during good weather. If it is cloudy or rainy, it is best if you can recite it during day time. You should avoid reciting the Heart Sutra after 10PM, or during extreme weather, including heavy rain, thunderstorm, and lightning.
Prayer: Before reciting this sutra, you can say your prayer or wish as follows, “May the Great Merciful and Great Compassionate Guan Yin Bodhisattva protect and bless me, <your full name>, grant me wisdom, a pure mind, calmness; and help me to be free from afflictions (maintain focus while performing recitations).”
