King Cyrus was the one who proclaimed that the Jews could now return to Israel (Judea) from their Babylonian exile. Certainly there must have been an upsurge in Thanksgiving to God, and a surge in the study of the laws that would once again be accessible, such as ritual purity.
However, Jews "look to their religion" every day of every year. It is a command to study and keep the Torah all the time (Deuteronomy ch.6), and that is what Jews have always done.
Jews consistently looked to their religion in that period (before, during, and after Cyrus). There was no special change in Jewish outlook that occurred under Cyrus the Great. What was notable about Cyrus' Rule was that he openly permitted the Jews to rebuild their Temple and practice their religion openly. This sudden political change became manifest in the rebuilding of Israel during that period.
Because of his tolerant attitude, Cyrus permitted the Jews to return to Israel (Judea) and rebuild the Temple.
