iTunes My Music - Allowing Explicit Content Disabled (personal library)
It looks pretty clear to me.
Apple are obeying the laws of the country you live in, presumably India judging by the number of Google hits I see for this issue.  

Your only possibility would be to try to change your iTunes Store Country - but that would be dependant on you being able to provide a credit card from that country.

See Apple KB - Change the country of your iTunes Store...
