Sri Yantra drawing course is not just about drawing and painting Sri Yantra. Before painting each of the 9 levels (avaranas) of Sri Yantra, we are also meditating on this exact aspect of the Divine Mother within ourselves and we focus on exact chakra to purify ourselves from within.
Sri Yantra consists of 9 mandalas which are leading us towards Divine. Each part of Sri Yantra represents one of our chakras, one part of our body and one of our nadis, energy channels in our subtle body. Ultimately, as Paramahamsa Vishwananda explained, the whole universe is present in Sri Yantra. It is not so much about drawing and painting Sri Yantra in the outside, but more about engraving it into our energy system. It is a very deep process of self-transformation and rising towards the Divine. The meditation itself, even without painting, is an extremely beautiful and powerful experience.
