I know after 'instead of' verb-ing is used. But I have found a sentence :
"My father wants me to be bold instead of be cautious".
Is it correct?
Can we use 'instead of being cautious' in the above sentence? Please clarify it.
The sentence is wrong, although not because of the word "be". Ideally, the sentence should use "rather than" and not "instead of". "Rather than" is coordinating; "instead of" is subordinating.
My father wants me to be bold rather than be cautious.
You could also drop the repetition of the verb and just say:
My father wants me to be bold rather than cautious.
