Yoga nidra or yogi sleep has been used for thousands of years by yogis. In the Upanishads, there are three states of consciousness: waking, dreaming and deep sleep. Yoga nidra allows an individual to leave the waking state, move past the dreaming state and into deep sleep while remaining awake or conscious during the whole process. In yoga nidra, there are no dreams to explore. Instead, it is a process of emptying. It purifies the deeper aspect of the human mind by exploring deep impressions or samskaras. This is essential as samskaras drive our karma.
Devavani means "divine voice," the energy of existence which moves through the meditator, who becomes an empty channel of expression. If done in the evening, it deeply relaxes the mind and creates a profound sleep and inner peace.Devavani meditation lasts for one hour. There are four stages of 15 minutes each. Keep your eyes closed throughout.
