This is a Prai Tai Tong Glom Nam Man Prai that is incredibly potent. This oil contains the oil and effigy of Mae Khalong, a woman who died while pregnant giving her ghost an extra intensity and who Ajarn Surak then worked with by mixing with 108 charm plants and sacred oils, and then offering Merit and blessings in order to bestow coherence and beneficence upon her. Ajarn then arranged a pact that Mae Khalong will happily help her caretaker in exchange for offerings and good deeds done in her name

Light 16 incense to your land spirits (or whatever makes sense for your unique relationship to them) and ask them to open the way for your new spirit friend to enter when she first arrives. She likes to face west and to have a glass of fresh water near by. When a wish is fulfilled, reward her with white alcohol, flowers, cigarettes, or sweets. When it comes to Merit, the more the better. Get creative with your good deeds and offer them to her in your mind, and do this liberally for best results.
