You have no eyes to see the length and breadth of the point. You are so blunt, your senses are so limited, imperfect, that you cannot imagine that a point can have length and breadth. But we get information from Vedic literature, not only the point, but one ten-thousandth part of the point is measured. Keśāgra-śata-bhāgasya śatadhā kalpitasya ca, jīvo bhāgaḥ sa vijñeyaḥ (Śvetāśvatara Upaniṣad 5.9).
Because we have no imagination, we have no instrument, neither we have sufficient knowledge what is the length and breadth of the form of the living entity. Therefore Vedic literature gives you an idea that you just try to imagine one ten-thousandth part of the point, and that is the measurement.
- keśāgra-śata-bhāgasya
- śatadhā kalpitasya ca
- jīvo bhāgaḥ sa vijñeyaḥ
- sa ānantyāya kalpate
- (Śvetāśvatara Upaniṣad 9)
So living entities, spiritual spark, that measurement is given there. Whenever there is measurement, there is form. It is not . . . but because we cannot see the form, we say nirākāra. It is our incompetency. Just like I cannot see beyond this wall. My seeing power is limited. Therefore I see there is nothing beyond this wall; there is nothing beyond this room. That's not fact. There is everything. I can see the sun, which is fourteen hundred thousand times bigger than this planet, but my eyes are seeing, daily, just like a disc. So don't believe your senses. Your senses are imperfect. Whatever knowledge you get by experimental knowledge, experimental method, that is the modern ways of understanding. But these things cannot be experimented.
Therefore we have to take the knowledge from the Vedas.
