What Other Things Must We Do Before We Decorate the Sacred Shrine?

this question answering by MahaGuru Liensheng.

After the room has been chosen for the shrine, and before is its decorated, we must first purify the room. This is because the room may have been used as a bedroom, office, study or store before, low spirits may have been residing therin. That is why apart from cleaning the place, you need to purify the place too. The simplest way to do so is to choose an auspicious day and spray some holy water empowered with the Great Compassion Mantra (Ta Pei Cou) from within to without the room.

By using the holy water to purify the room, all evil spirits will be driven away, as they can no longer remain in the room. Thereafter, when the practitioner does his practice in the sacred shrine, he will not be frightened, and no evil will disturb the practitioner’s mind. For the room has been throughly purified. There are many ways of purifying the room. For a True Buddha practitioner, it is best to use the Great Compassion Mantra for empowering the holy water.
