There are two main types of eclipses: a solar eclipse, and a lunar eclipse.
A solar eclipse is where the Moon covers the Sun. In Jyotish, this represents your emotional mind (the Moon) covering the Sun (your soul). A lunar eclipse, on the other hand, is where the Earth goes in between the Moon and the Sun. This represents material energy (the Earth) blocking the Sun’s rays (the light from your soul) from reaching your mind (the Moon).
Eclipses disrupt the energy that make up our universe, so it is generally seen as negative times to start anything important, like buying a house, signing a contract, or starting a new job. The material energy is disrupted intensely 3 days before and after any eclipse, and this affects the whole world and all its inhabitants. In addition to this, eclipses can affect certain individuals for up to 6 months if the eclipse happens to take place over one of the person’s birth / natal planets.
In some parts of the world, eclipses are seen as very negative and unlucky events. In India and other parts of Asia, when an eclipse is taking place, people will stay in their homes or go to a temple, and close the blinds to the outside world. It is seen as inauspicious to look at an eclipse. This is an external representation of what we should do inwardly - we should be closing the blinds to the external world and going deeper within ourselves.
If you understand what eclipses are, you’ll realize that eclipse times are actually a really great time to meditate, reflect, and to go inward. The disrupted material energy thins the veils covering our soul, and this allows us to more easily realize that, at our core, we are spirit souls and thus eternally blissful. This is Jyotish in a nutshell - reading the language of the universe to help you optimize your time, align your life to your true purpose, and guide you on your spiritual journey. So, may you use these eclipses to serve your higher purpose, and to go deeper into your true self.
