When Maricha cried out: "O Lakshmana, O Sita," Sita mistook it for Rama's voice. She could not identify Rama's voice as different from that of another, though she had lived with Rama for so long. So is the case with the Jiva. It has forgotten its association withthe Absolute and cannot distinguish the call of the Spirit from the clamours of the senses. This is called delusion.
