Bhagavad Gita 5.4

साङ्ख्ययोगौ पृथग्बाला: प्रवदन्ति न पण्डिता: |
एकमप्यस्थित: सम्यगुभ्योर्विन्दते फलम्

Translation

Only the ignorant speak of sānkhya (renunciation of actions, or karm sanyās) and karm yog (work in devotion) as different. Those who are truly learned say that by applying ourselves to any one of these paths, we can achieve the results of both.
