Raahu Gayatri

om naakadhwajaaya vidmahae 
padma hastaaya dheemahi 
tanno raahu: prachodayaat

Om, Let me meditate on him who has snake in his flag,
Oh, He who has a lotus in his hand, give me higher intellect,
And let Rahu illuminate my mind.

tanno ketu: prachodayaat

Om, Let me meditate on him who has horse in his flag,
Oh, He who has a trident in his hand, give me higher intellect,
And let Kethu illuminate my mind.
