Kemayan is a kind of incense (raw stones), put in a burner (shaped like alladin's lamp) with a cinnamon stick, burn until white clouds come out and go from one corner of the house to every single corner while chanting.
First time I got it from Little India, think by fate it's the wrong one, ending up from using matchsticks to using gas, from outside the house to inside the house.
But later I lazy buy those ready made kemayan incense shaped like a yuan bao from those incense paper shops. Later my husband continued with this incense cleansing very often.
Oic, I think I saw them before in incense paper shops. Thanks for sharing.
