If we look at space with the naked eye, we might see the brightest stars and the nearest heavenly bodies, but we will neither see the faint lights nor the remote planets. If we look at a drop of pond water with the naked eye, we might not see that it is teeming with life. Thus, we should never project our own limitations onto reality, and arrogantly assume that our imperfect findings are the final and objective ‘truth’.
In the same way, when mere logicians investigate ultimate reality, they apply their limited intellectual and spiritual capacities to the task, and ―finding nothing― they dismiss as ‘heretical’ and ‘extreme views’ the direct yogic perception of Buddha Nature, and deride the sutras of the Third Turning of the Wheel of Dharma as ‘provisional’.
‘Not finding’ and ‘not existing’ are not identical, and absence of proof is not proof of absence.
“Emptiness cures wrong views, but the view of emptiness is incurable.” ―Arya Nagarjuna
