The following was posted to the Advaitin List by Satyan Chidambaran, who has agreed for me to record it here.

There is a distinction between bAdha (sublation) and nAsha (destruction) that the tradition makes.

To know that a Pot is not real, and only clay alone is real, one shouldn’t need to destroy (engage in nAsha of) the Pot appearance. One just needs to know clearly that the Pot is just a name and form and Clay alone really exists. Therefore, even when seeing a Pot, a “Clay j~nAnI” knows clearly that the Pot is mithyA nAma rUpa and Clay alone is satyam. This is bAdha of the Pot.
