Khandro Déchen comments:
Phurbas are shown in various different ways. They are either depicted with vajra handles or in the simplified form of gTérma phurbas. When they are shown with vajra handles
– these can be five- or nine-prong vajras. Here – the five-pronged vajra handles of the phurbas symbolise the transformation of anger according to the five neuroses.
The nine prong vajra handles symbolise the activity of the phurba throughout the nine
skies.
