Bhagavad Gita Chapter 2 Verse 66

Translation: A man who has not overpowered his mind and senses does not have steadfast intellect and in the inner-self of that man with uncontrolled mind, there are no emotions. And an emotionless person does not attain peace. How can a person devoid of peace attain happiness?

Meaning: - A devotee whose doubts are not cleared i.e. who does not find a Tatvdarshi saint, as a result of which instead of doing bhakti of one Supreme God, keeps performing various other religious practices and desiring different things. That devotee does not gain anything.
