I suggest you look at your responses to my words a little more closely... Id is short for 'identity', please tell me how this differs from ego... As best I can see, id is a particular identification and ego is the collection thereof, if you are really making the distinction on these grounds, please headbutt your nearest wall right now.
Id "Id, ego and super-ego are the three parts of the psychic apparatus defined in Sigmund Freud's structural model of the psyche; they are the three theoretical constructs in terms of whose activity and interaction mental life is described. According to this model of the psyche, the id is the set of uncoordinated instinctual trends; the ego is the organized, realistic part; and the super-ego plays the critical and moralizing." From wiwki. "It is the dark, inaccessible part of our personality, what little we know of it we have learned from our study of Dreamwork and of the construction of neurotic symptoms, and most of that is of a negative character and can be described only as a contrast to the ego. We approach the id with analogies: we call it a chaos, a cauldron full of seething excitations... It is filled with energy reaching it from the instincts, but it has no organization, produces no collective will, but only a striving to bring about the satisfaction of the instinctual needs subject to the observance of the pleasure principle." Sigmund Freud, New Introductory Lectures on Psychoanalysis[1933] (Penguin Freud Library 2) p. 105-6. The Id is not an ID.... it is a construct (model) of the unconscious mind in paychology.
Ahh, but here the Pali does not say bhavanga-citta--it just says citta. (At the beginning) Where it refers to development of the mind it says cittabhāvanā. 1. 5. 9. Pabhassaramidaṃ bhikkhave cittaṃ, tañca kho āgantukehi upakkilesehi upakkiliṭṭhanti. 1. 5. 10. Pabhassaramidaṃ bhikkhave cittaṃ, tañca kho āgantukehi upakkilesehi vippamuttanti. Vaggo pañcamo46 [BJT Page 020] [\x 20/] 6. Pabhassaravaggo 1. 6. 1. Pabhassaramidaṃ bhikkhave cittaṃ tañca kho āgantukehi upakkilesehi upakkiliṭṭhaṃ. Taṃ assutavā47 puthujjano yathābhūtaṃ nappanājāti. Tasmā assutavato puthujjanassa cittabhāvanā natthīti vadāmīti. 1. 6. 2. Pabhassaramidaṃ bhikkhave cittaṃ tañca kho āgantukehi upakkilesehi vippamuttaṃ.48 Taṃ sutavā ariyasāvako yathābhūtaṃ pajānāti. Tasmā sutavato ariyasāvakassa cittabhāvanā atthīti vadāmīti.
Bhikkhave is just another transliteration... please keep in mind Pali doesn't use Latin letters. Your own original link says Bhavanga was intended, and so I have addressed this...
