Upanishadic stages of awareness (Hinduism)

In the Chandogya Upanishad, it is said that a person must learn to worship Spirit in sixteen aspects. First as [nama]

(name), then as [wac]

(speech), as [manas]

(mind), [sankalpa]

(resolution), [citta]

(mind's mother substance), [dhyana]

(meditation), [vidya]

(knowledge), [balam]

(power), [anna]

(food), [apa]

(water), [tayjas]

(light), [akasha]

(ether), [smara]

(memory), [asa]

(hope), [prana]

(life) and finally [satya]

(truth). Having come to worship each of these as Spirit, the individual knows, speaks, thinks, is devoted to, acts and finds happiness in the truth beyond discussion, the unlimited.
