Bardo refers here to the mind in the intermediate state after death or when the consciousness is separated from the previous body. It is the state between the past life and the next coming life. The mind born in Bardo gets a mental dream-like body, which can leave and reach anyplace any time without any obstacles. The maximum duration of the Bardo is 49 days but, at any time, the consciousness may achieve its new life under any form in any of the six realms mentioned in Buddhism. It totally depends on the past lives karma and especially on the karma earned just in the previous life. The Bardo life is made of suffering from the non-acceptance of one’s death and the attachment to oneself and family, friends, possessions, etc.
The ‘Tibetan Book of dead‘ explains in detail the Bardo hallucinations and experiences and introduces to the self the recognition of the illusory body and mind. The kusum-lamkhyer practice, ‘taking the three Kayas into practice‘, is a daily life practice for the preparation of dying, Bardo and reincarnation.
