Can I heal myself by imagining white light pouring through my aura daily?

Namaste, Ayaan. Your practice of visualizing white light is a form of Manasa Puja (mental worship). It is far more than a coping mechanism. The Astrological Reason: As a July birth, your Sun is strong, and white light is the frequency of the Sun and Moon combined (purity and vitality). You are effectively "charging" your aura with Sattva Guna. The Solution & Remedy: It is an energetic fact. The mind follows the breath, and energy follows the mind (Yato Manas Tato Prana). Enhancement: Use a Clear Quartz (Sphatik) crystal while meditating. It acts as a transducer, taking your mental imagery and amplifying it into a tangible energetic frequency. Technique: Imagine the light entering through the Crown (Sahasrara) and expanding outward like a golden-white egg. This creates a "Vajra" or diamond-shield around you.
