The ceremony involves praying to the spirit of the jungle, mountain, cave or other god that protects the area. 

Lek-lai at source before being cut  

The full ceremony is far too involved to detail here, but essentially involves the following: First offerings and prayers are given to ask permission to remove the leklai. The prayer used:
 

Failure to honour the promises made during that ceremony may result in death. It has also been said that during the ceremony, an amulet or other protective talisman should be worn as protection from the spirit residing in the leklai which may try and disturb the ceremony.
 

If the power of the mind of the forest monk who is performing the ceremony is higher than the spirit that resides / protects the Leklai, then the Leklai will slowly melt out from the rock. The monk may use honey to lure the Leklai. The Leklai will flows towards the honey.

During this period the monk is required to use Sai-Sin to tighten the Leklai at the bottom of the rock. This is to both prevent the Leklai from reversing back to rock and general protection from spirits. This part of the ceremony is very involved an requires the use of numerous staffs or sticks cut from the surrounding jungle inscribed with magical Khmer incantations
