Placing a representation of Surya Dev (the Sun God) on the east-facing wall at a height of seven feet is a common practice rooted in Vastu Shastra, the traditional Indian system of architecture.

1 Vastu principles emphasize aligning buildings and their interiors with natural forces for positive energy flow.
2 The east is considered an auspicious direction, associated with the rising sun, new beginnings, and vitality.
3 Placing Surya Dev in this direction is believed to bring positive energy, health, and prosperity to the inhabitants.
4 The specific height of seven feet is likely intended to position the image at a respectful eye level, making it a focal point without being overly dominant. While these practices are based on traditional beliefs, they are often followed by those seeking to create a harmonious and positive living environment. Whether or not one ascribes to Vastu principles, the image of Surya Dev can serve as a beautiful and inspiring focal point in the home.
