Bhagavad Gita 2.41

व्यवसायात्मिका बुद्धिरेकेह कुरुनन्दन।बहुशाखा ह्यनन्ताश्च बुद्धयोऽव्यवसायिनाम् ॥२.४१॥

vyavasāyātmikā buddhirekeha kurunandanabahuśākhā hyanantāśca buddhayo’vyavasāyinām

Here, O joy of the Kurus, there is only one single-pointed determination; many-branched and endless are the thoughts of the indecisive.
