This amulet was made in 2552 to commemorate the 50th anniversary of the passing of LP Sodh. I really like that it depicts him teaching the meditation.
The actual diagram the master used to teach is now housed inside the stupa.
The reverse side shows the position of the five elements as experienced in the seventh position, shown here next to an image from the English meditation manual
