Shunya is the Sanskrit term translated in English as Void & also as Nothingness. The Madhyamika School of Buddhism that shunya is the transcendent & indefinable & immanent in all beings. Scholars speaking for shunya say that it is not nothingness since even the illusory structure can’t be sustained in nothingness. Void is a metaphysical reality. Nagarjuna, the scholar, logician of the said school says Shunyata is a positive principle. Kumarajiva, commenting on Nagarjuna mentions that it is on account of Shunyata that everything becomes possible (Prajnaparamita). From the Madhyamika point the reality is Shunya (Shunyam Tattvam).
