The gemara in Brachos [ה] gives 3 eitzos how to overcome the yetzer hara: 1] Torah. 2] If that doesn't work then read Shma. 3] If that doesn't work remember your day of death.
The gemara in Kiddushin doesn't seem to feel that all 3 eitzos are necessary. The gemara says simply בראתי יצר הרע בראתי תורה תבלין. Torah and Torah alone is the antidote for the yetzer hara.
So which one is it? Do we need all three or is Torah enough???
