In Vastu Shastra, a North West Helix (specifically a Brass Helix) is the remedial tool used for the Vayavya (Air) corner. This direction is governed by the element of Air and ruled by the planet Moon and the deity Lord Vayu.

Because Air is inherently mobile, the North West corner governs movement, travel, relationships, and networking.

Why Brass?

The North West corner sits at the intersection of the West (Space) and North (Water) energies. Brass is the chosen metal because its golden hue and composition harmonize the Air element, providing stability to the otherwise “fickle” nature of the wind.

Common Vastu Defects Corrected

A Brass Helix is installed when the North West corner is compromised by:

The “Blocked Air” Defect: If the North West is completely closed off (no windows or ventilation), causing stagnant energy in the house.
Incorrect Room Placement: Having a Master Bedroom here (which should be in the South West) can lead to a “restless” mind or frequent, unnecessary travel.
Extensions or Cuts: If the North West corner is missing from the floor plan, it can lead to legal issues or a lack of support from friends and neighbors.
Toilets or Kitchens: While a toilet is often acceptable in the North West, if it is not properly balanced, it can cause “financial instability” or “fluctuating luck.”

Benefits of the North West Helix

Social & Business Support: This corner is known as the “Support Corner.” The Helix helps you get help from the right people at the right time (investors, mentors, or helpful neighbors).
Smooth Travel & Relocation: If you are facing delays in visa processing, immigration, or moving to a new home, this remedy helps clear the “pathway.”
Stable Mindset: Since the North West is ruled by the Moon, a defect here can cause mood swings or anxiety. The Helix helps calm the mental “winds.”
Inventory Turnover: For business owners, placing a Helix here helps move “dead stock” or unsold inventory more quickly.

Installation & Placement

Material: High-quality Brass.
Quantity: Usually installed in sets of 3 or 9 for maximum effectiveness.
Placement:
- The Wall: Can be fixed on the North West wall or placed inside a North West cupboard.
- Main Entrance: If your main door is in the North West, placing 3 Helixes above the door frame helps filter out negative social influences.
- Underfloor: Can be buried in the North West corner of a plot or flat during renovations.
Activation: To “charge” the Air element, it is often suggested to light a high-quality incense stick near the Helix after installation.
