From Ribhu Gita, Chapter Five:

Six verses selected by Sri Ramana Maharshi (note: original verse numbers appear in brackets).

1) The concept 'I-am-the-body' is the sentient inner organ (i.e. the mind). It is also the illusory samsara. It is the source of all groundless fears. If there is no trace of it at all, everything will be found to be Brahman. (17)


2) The concept 'I-am-the-body' is the primal ignorance. It is known as the firm knot of the heart (hrdayagranthi). It gives rise to the concepts of existence and non-existence. If there is no trace of it at all, everything will be found to be Brahman. (19)


3) Jiva is a concept, God, the world, the mind, desires, action, sorrow and all other things are all concepts. (25)


4) The mind is unreal. It is like a magic show. It is the son of a barren woman. It is absolutely non-existent. Since there is no mind there are no concepts, no Guru, no disciple, no world, no jiva. All concepts are really Brahman. (36)


5) The body, etc., are only concepts. Hearing, etc. (i.e. hearing, reasoning and contemplating) are concepts. Self-enquiry is a concept. All other things are also concepts. Concepts give rise to the world, the jivas and God. There is nothing whatever except concepts. Everything is in truth Brahman. (30)


6) Abiding without concepts is the undifferentiated state. It is inherence (in Brahman). It is wisdom. It is Liberation. It is the natural state (sahaja). It is Brahman. It is Siva. If there is no concept at all everything will be found to be Brahman. (26)
