In Sanskrit, Visoka va jyotismati translates to the light within which is free from all suffering and sorrow. What is noteworthy about this Yoga Sutra is that it does not contain any specific instructions. Instead, it simply offers the image of jyotismati, or our inner light, free from sorrow or grief (visoka)—and purposely leaves the way open for the application of the sutra to vary according to each person's individual needs and beliefs.
The Yoga Sutras describe this light as a great brightness or radiance in the heart, from which the true Self shines forth. The light has also been described as a tiny spark on the tip of a thread in the darkest recesses of a cave within the heart. For me, the image of the thread with a bit of light at the tip has always symbolized that no matter how far removed or disconnected you may feel from the light, and no matter what your circumstances, the spark of that light always lies within, free from grief, from pain, from sorrow and affliction.
Even when you've forgotten about the light or doubt its existence, it's there—and remembering and reflecting on that can be can be a great source of support and comfort in difficult moments. Depending on your personal beliefs, this sutra might evoke and support your connection with God, the Universe, or a higher power. When you connect with that light, you can cultivate it, bring it forth into your everyday life, and share it with the world around you. This sharing need not be any specific outward action or display and in fact might be quite subtle.
You might share your light with others by cultivating or deepening your sense of wonder, joy, or compassion, thus affecting your way of being in the world. Sharing your light might mean deciding to volunteer, or simply inspiring others through the quiet reflection or inspiration behind your actions and deeds in the world, whether it's offering quiet support to another in need or a smile to a stranger. However your deepening connection with your inner light manifests, when you cultivate it, you will come to know this source of inner support that's always there to help you find a greater sense of peace and ease, even in the darkest of times.
