Yes
Is this essential that my paypal account verified ?
If you intend upon being successful in your business I say yes

There are limits on how much you can withdraw as unverified and if successful, you will not want the low withdrawal limit

Thanks for your nice answer kobra .
other question is my account is not a business account , is there any problem if I use Personal Paypal Account ?

No but as a business you should either create another or convert yours to a business account

The maintaining of personal as personal and business as business is a major factor when tax time comes around

For an online store, you must have a "Premier" or a "Business" account.

A "personal" account cannot be used to receive payments from an online store.

I use Paypal API for my shop , and set all things in my paypal account and zen cart Admin for ex : i set Store/ipn_main_handler.php in paypal account and Store/index.php?main_page=checkout_process in paypal account , but customers can not send for me the money ! . Is this Problem for my unverified Paypal account ?
Please help me .
Thanks

You need to talk to PayPal.

Thanks .
