This sloka is for Lord Ganesha, the remover of obstacles. This sloka is to be recited on Sankatahara or Sankashti day - that is the chaturthi following full moon in place of Ganapathi Sahasranamam or other rituals demanding too much time.
Om Pranamamya shirasa devam gowriputhram vinaayakam
Bhaktavaasam smarenithyam ayuh kaamaartha sidhaye
Prathamam vakrathundam cha ekadantam dwithiyakam
Thrithiyam krishnapingaaksham gajavakram chathurthakam
Lambodharam panchamancha shashtam vikatamevacha
Sapthamam vighnarajendram cha dhoomravarnam thathaashtakam
Navamam balachandram cha dashamam thu vinaayakam
Ekadaksham ganapathim dwadasham thu gajaananam
Dwadashitaani namaani thrisandyaam yaha pa te naraha
Na cha vighnabhayam thasya sarvasiddhikaram prabho
Vishyaarthi laabathe vidhyaam dhanaarthi laabathe dhanam
Puthraarthi laabathe puthraan mokshaarthi laabathe gathim
Japedh Ganapathi sthothram shadbhir masam phalam labathe
Samvathsarena siddhim cha laabathe nathra samshayaha
Ashtebhyo brahmanebhayashcha likithvayaaha samarpayeth
Thasya vidya bhaveth sarva ganeshasya prasaadathaha
Iti sri narada purana
Sankashtana naashana ganapathi sthotram samaptham
