sri rama rama rameti rame rame manorame
sahasranama tat tulyam rama nama varanane
This translates to:
O Varanana (lovely-faced lady), I chant the holy name of Rama, Rama, Rama and thus constantly enjoy this beautiful sound. This holy name of Sri Rama is equal to one thousand holy names of Lord Vishnu." (Brhad Visnusahasranamastotra, Uttara-khanda, Padma Purana 72.335)
sahasra-namnam punyanam, trir-avrttya tu yat phalam
ekavrttya tu krsnasya, namaikam tat prayacchati
This translates to:
"The pious results (punya) achieved by chanting the thousand holy names of Vishnu (Vishnusahasranama-Stotram) three times can be attained by only one utterance of the holy name of Krishna."
yo mam nama sahasrena stotum icchati pandava
sohamekena slokena stuta eva na samsaya
This translates to:
"Arjuna, One may be desirous of praising by reciting the thousand names. But, on my part, I feel praised by one sloka. There is no doubt about it.”
