>> Asoka after embracing Buddhism discontinued this practice and removed the idols of such deities.
The meanig of the sentence is clear. According to Dr. Ambedkar Aśoka 'removed the idols of such deities'.
Removed - gently?
The problem is that no edict mentions Aśoka stating: "As I venerate the Buddha, the Enlightened One, there is no need to worship any other deity".
The question of 'the emergence of images and idols in India" apart what can be seen here is an example of falsification of historical record, done purposefully, with political agenda in mind.
