This is a prayer offered to lord Ganesh to remove all obstacles from the path to success in the task/goal we are about to start / pursuing. This is prayed before starting any new work. This is very important prayer for Hindus.

प्रसन्न वदनम् ध्यायेत्
I meditate upon the Lord Ganesha who is clad in white garment (dhoti), who is pervading, who is as bright colored as Moon, who has a smiling face, having four shoulders (or hands), and who is the remover of obstacles.
Note: The word ‘Vishnum’ is not meant for lord vishnu. vishnum in this sloka means pervading.
