Varanasi is a sacred place indeed. When you will go there and stay for 2 days your mind and soul will be full of devotion. To enter into temple you must hire a local priest and they don’t charge more. They manage everything and let you in the annapurna temple where you can see golden idol. Varanasi has 786 alleys and all looks identical, so keep the address of your hotel along with you .
If you are lost then just show it to any rikshaw driver and they will carry you to your hotel. There are near about 80 ghats in varanasi. so hire a boat and they will show you all the ghat. Take a dip in ganges and release all your sins.
