Sharp Corner Sha — pointing corners in feng shui

Meaning and Context

Jian Jiao Sha (尖角煞) literally means "sharp corner sha." In feng shui, pointed or angular shapes are considered to concentrate and project energy outward. When such a point aims at a building, room, or person, it creates a form of Sha Qi.

This concept applies at multiple scales—from large building corners pointing at your home, to interior furniture corners pointing at your bed or desk.

  • Exterior sources: Building corners, roof points, decorative spires
  • Interior sources: Furniture corners, exposed structural edges, angular decor
  • Effect: Directed, aggressive energy toward the target
  • Associations: Conflicts, accidents, health issues in the targeted area
Psychological element
There is a psychological component to Sharp Corner Sha—pointed shapes aimed at us can create subconscious unease. This may contribute to the effects traditionally attributed to this sha.

Classical Roots

Classical texts warn about pointed shapes:

From Yangzhai Sanyo
「屋角射门,主口舌是非。」
Plain translation
"A building corner shooting at the door brings arguments and disputes."

The language of "shooting" (射) emphasizes the directional, aggressive nature of the energy from sharp corners.

Types of Sharp Corner Sha

Sharp Corner Sha manifests in various forms:

  • Building corners: Adjacent buildings with corners pointing at your entrance or windows
  • Roof points: Triangular roof peaks or decorative elements aimed at you
  • Wall corners: Interior or exterior wall edges that create pointed angles
  • Furniture: Desk corners, table edges, cabinets pointing at beds or seating
  • Decorative items: Sharp sculptures, arrow-shaped objects, pointed plants

Severity depends on sharpness of the angle, proximity, and whether it points at important areas (doors, beds, desks).

Remedies for Sharp Corner Sha

Solutions for different situations:

  1. Exterior corners: Block with trees, screens, or curtains; use deflecting objects
  2. Interior corners: Round the corner with plants, fabric, or corner guards
  3. Furniture: Reposition to avoid direct pointing; choose rounded furniture
  4. Symbolic: Use protective symbols or Five Element cures in affected areas
  5. Distance: Increase distance between the corner and important positions
Practical approach
The simplest interior remedy is repositioning. If a furniture corner points at your bed, move the bed or the furniture. Physical changes are more effective than symbolic cures.

FAQ

Does every corner create Sharp Corner Sha?

+
No. Sharp Corner Sha requires two conditions: the corner must be pointed (acute angle is worse than obtuse), and it must be aimed at something important (door, window, bed, desk, or seating area). A corner that faces away from you, or a rounded corner, does not create this sha. The concern is specifically about pointed shapes directing energy toward occupied spaces.

How do I fix Sharp Corner Sha from furniture I cannot move?

+
If you cannot reposition the furniture, try these alternatives: cover the corner with a cloth or plant, apply a corner guard to round the edge, place an object between you and the corner to block the direct line, or hang a faceted crystal ball to disperse the energy. Choosing furniture with rounded edges for future purchases is also advisable.
