ST-2 - Four Whites
四白 - Sì bái
Point Region: Face
ST-2 Sibai, meaning 'Four Whites,' is a key point for brightening the eyes and calming muscle twitching around the eye. Located in the infraorbital hollow, this point is like a beacon of clarity for the face, helping to clear heat and soothe a restless spirit. The name 'Four Whites' refers to the white of the eyeball and its ability to restore a sense of calm and clarity.
Think of Sibai as a point that helps you to 'see the light.' It's invaluable for addressing issues like red eyes, a twitching eyelid, and a feeling of being 'overwhelmed.' By brightening the eyes and calming twitching, it helps to restore a sense of ease and clarity to the face.
By brightening the eyes and calming twitching, ST-2 helps to restore a sense of balance and inner peace. It's a point that reminds us that our true power comes from a calm and clear mind.
