The All-Embracing Measure
'Dimensions' are merely our conceptual extension in 'Space', which appears in three divergent directions of measurement as length, breadth, and height, a fourth, spatially incognisable but called 'voidness', being phenomenally represented by duration.
It is this latter which represents our apparent being, for we appear to exist because we appear to last. Our continuation in time, long or short, our growth and development therein, our process of being born, maturing, ageing and dying seems to take place, or be extended as we say, in 'time', so that what we are is seen to be that lasting, becoming, in the framework of 'space'.
Our appearance must be dependent on the concepts of 'space' and 'time', for without them we could not appear to be, and without us they are not at all. They are our apparent extension, three directions of measurement conceived as spatial dimensions, the fourth as temporal.
As has been demonstrated herein, there is no past, no future, and the 'present', i.e. existence as such, is no moment, but is this temporal dimension which includes all the others, and so represents what we can be said to be.
Being is Becoming
'Absolute voidness devoid of differentiation', as envisaged by Nagarjuna, is represented by this further all-embracing continuum.
As is also what is called 'Buddha-mind', and ours.
It is termed 'mind' or 'heart' (hsin),
It is Suchness too, and it is Nirvana, and Noumenon.We can only speak of it correctly in the first-person-singular, for it is no 'thing', is objectively nil, but we know it as 'Eternity', as duration, as becoming.
So we are what 'time' is, and what 'time' is we are,
And 'time' is the all-embracing measure of space.
