7.14.29

यत्र यत्र हरेरर्चा स देश: श्रेयसां पदम् । यत्र गङ्गादयो नद्य: पुराणेषु च विश्रुता: ॥ २९ ॥

yatra yatra harer arca sa desah sreyasam padam yatra gangadayo nadyah puranesu ca visrutah

yatra yatra
wherever
hareh
of the Supreme Personality of Godhead, Krsna
arca
the Deity is worshiped
sah
that
desah
place, country or neighborhood
sreyasam
of all auspiciousness
padam
the place
yatra
wherever
ganga-adayah
like the Ganges, Yamuna, Narmada and Kaveri
nadyah
sacred rivers
puranesu
in the puranas (supplementary Vedic literature)
ca
also
visrutah
are celebrated.

Auspicious indeed are the places where there is a temple of the Supreme Personality of Godhead, Krsna, in which He is duly worshiped, and also the places where there flow the celebrated sacred rivers mentioned in the Puranas, the supplementary Vedic literatures. Anything spiritual done there is certainly very effective.
