The explanation of Phor Slang Ngeng is a little long and complicated. But just note that He originated from Hinduism and is a deity. HE has no physical body like higher deities but just an Astral form. So when we offer rice wine as an offering to give thanks, we usually dabs on His mouth.
People who worship Slang Ngeng asks for business or wealth improvement. And also for a life partner. Also worship for Phor's powerful Maha Saneh ❤️
