When you can afford it, you may wish to invest in a copy of the Majjhima Nikaya translated by Bhikkhu Namamoli and Bhikkhu Bodhi. I find the Ven Namamoli and Bhikkhu Bodhi's translations more reliable and it includes a wealth of explanatory notes.
(THE BASE OF NOTH|NGNESS)
8. "Again, bhikkhus, a noble disciple considers thus: 'I am not anything belonging to antone anywhere, nor is there anything belonging to me in anyone anywhere (1016)'. When he practices in this way and frequently abides thus, his mind acquires confidence in this base. Once there is full confidence, he either attains to the base of nothingness now or else he resolves [upon it] with wisdom. On the dissolution of the body, after death, it is possible that the evolving consciousness may pass on [to rebirth] in the base of nothingness. This bhikkhus, is declared to be the third way directed to the base of nothingness
MA calls this four-pointed voidness and explains thus: (i) he does not see his self anywhere; (ii) he does not see a self of his own that can be treated as something belonging to another, eg: as a brother, friend, assistant, etc.; (iii) he does not see the self of another; (iv) he does not see the self of another that can be treated as something belonging to him. Ms has a note by Nm: "These expressions [in this paragraph and the next] seem to have been stereotyped slogans or descriptions of the attainments of nothingness and neither-perception-nor-non-perception, primarily non-Buddhist, and sometimes used as a basis for the existing-body [=identity] view." See Nm's note 19 to Vsm XXI, 53 for further discussion and other references.
