Mitra is another name given to the Sun, which means "a friend". A friend is someone who is constant and brings warmth and lightness in our heart. This is why the sun is called so, as to whether we are grateful or not the sun continues to be there and offer these positive qualities without expectation.
Listen to this Mitra holding the visualization that you will be a good friend to those around you. That you will be a beacon of light and warmth for yourself, your family and friends.
Listen to it 12 times, once in the morning and once in the evening.
