The dream is actually a good example for both. For Ishwar or God, who is consciousness, but God's power, Maya, that is an object in consciousness. Om Chantesh ChanteshChantesh, Hare Jom, that's Sree Ram Krishna, Upanamastu.
Swami Sarvapriyananda teaches the Katha Upanishad, which is one of India's most revered texts and a part of the Vedas. It is a collection of philosophical poems representing a conversation between the sage Naciketas and Yama (god of death). They discuss the nature of Atman, Brahman and Moksha(liberation).
