The wicha Sariga Lin Tong is famous since hundreds of years in Thailand as a very powerful maha sanaeh charm for attracting lovers and invoking kama sutra magic. The local devotees of Luang Por Kong Sak have their own dialect; hence, they call the oil 'gua pho'.

The prai oil potion is made from herbs, oils, waxes, jasmine flowers, rak sorn, ga hlong, kaset bua tong flowers, bai sorn nang ram ('dancing lady leaf'), and rampong ga salak root.

The wicha Sariga Lin Tong is the charm of a golden tongued deva that softens your speech and convinces others with its coaxing spell of charm and attraction. Its powers are useful in jerajaa (business talk or selling by the gift of speech), and for charming others both socially and professionally. Principally, the oil is used for mercy and as a love charm to find a partner, or to receive mercy and friendly reception wherever one goes.

The pot has received inscription of Khom Angkhara spells and a sacred 'Na' on the lid for final empowerment.

The magical power of the see pherng is boosted with prai oils. The potion is mixed with many herbal prai powders, boiling them all together in a cauldron empowered previously with yantra inscriptions. The wooden paddle used to stir the potion was made from holy wood, and inscribed with powerful incantations in ancient Khmer (Khom) Agkhara lettering.

The Invocation of the Prai Spirits and the 4 elements, and the Akarn 32 Rital was performed along with the Nippana Suudt to empower the Prai Oil potion with the spirit of the Prai Devas and the power of Maha Sanaeh.
