Question: How can we tell what plane of consciousness our dreams come from?Sri Chinmoy: There are seven higher worlds and seven lower worlds. When we have dreams coming from the lower worlds, the subconscious worlds — or you can say, inconscient worlds — we have to feel that these dreams have no value. They cannot change our nature. They cannot inspire us. They cannot give us any hope for our future fulfilment. When we get a dream from the vital plane, we will see that the dream will be constant movement. It will be like a battlefield where everything is breaking and smashing and people are being killed. These dreams cannot help us at all in our spiritual life. The best thing we can do is forget them. If the dream comes from the mental plane, there will be some poise — not full poise, but a little poise, a little calm and quiet there. If it comes from the psychic plane, we will feel affection, sweetness, compassion and concern for the things or persons we are seeing. And if it comes from the soul's plane, it will be all Light, Delight and Peace.
