B.G 2.41
व्यवसायात्मिका बुद्धिरेकेह कुरुनन्दन। बहुशाखा ह्यनन्ताश्च बुद्धयोऽव्यवसायिनाम् ॥२-४१॥
vyavasāyātmikā buddhirēkēha kurunandana। bahuśākhā hyanantāśca buddhayō'vyavasāyinām ॥2-41॥
O Joy of Kurus, the understanding of those who strive methodically towards the essence, the ātman, the ultimate reality, is single certain knowledge. Those who are opposed to methodical striving have opinions that digress in multiple directions and are endless.
Gīta Bhāshya 2.41
Opinion determined by proper reasoning is single certain knowledge.
Krishna says - "Listen now to the understanding regarding Yōga". But if Arjuna doubts - "There are multiple understandings (regarding Yōga) because of differences of opinion, and how can I be faithful to all opinions simultaneously?". Then Krishna says - 'vyavasāyātmika'. The opinion determined by proper reasoning is single certain knowledge - is the meaning conveyed by the verse.
Gīta Tātparya 2.41
Ony those who are devoted to lord Vishnu will arrive at single certain knowledge.
"The understanding arrived at by reasoning various principles in one for those devoted to lord Vishnu. Those seeking material gain have diverse and many opinions." - states Brahma Vaivarta purāna
