During Tantric visualisation with a Yantra, take a moment to observe the intricate shapes and patterns present in the Yantra. Notice the precise arrangement of triangles, circles, lotus petals, and other geometrical elements. Explore the various parts of the Yantra with your eyes, tracing the lines and curves with your gaze. As you delve deeper into the visualization, allow yourself to feel the energy and symbolism emanating from the Yantra. Observe how the different shapes and patterns resonate within you, invoking specific emotions, sensations, or states of consciousness. As you continue your visualisation, try to imagine the Yantra in three dimensions, allowing it to come alive in your mind's eye. Feel the depth and presence of the Yantra as you immerse yourself in its sacred geometry. This practice can awaken a sense of connection, harmony, and physical insight within you, as you explore the profound depths of the Yantra's visual symbolism.
