एषा तेऽभिहिता सांख्ये बुद्धिर्योगे त्विमां श्रृणु।
बुद्ध्यायुक्तो यया पार्थ कर्मबन्धं प्रहास्यसि।।2.39।।
।।2.39।। हे पार्थ तुम्हें सांख्य विषयक ज्ञान कहा गया और अब इस (कर्म) योग से सम्बन्धित ज्ञान को सुनो जिस ज्ञान से युक्त होकर तुम कर्मबन्ध का नाश कर सकोगे।।
Having instructed the true knowledge of the soul as being distinctly different from the physical body and seeing that this knowledge has still not been firmly embedded in Arjunas heart, Lord Krishna reiterates this truth again in order to illustrate that this knowledge never becomes firmly embedded without practice of the means which is yoga. To do this He introduces the yoga path of selfless actions as the means to this end. Thus the reality is to perform all actions under the direction of ones mind well cultivated by the aid of spiritual knowledge from the Vedic scriptures exclusively. Although this spiritual knowledge is scientific Arjuna is still unsteady in its application due to lack of practice in assimilation. So Lord Krishna explains that by practice in the performance of actions by the renunciation of their rewards Arjuna will be completely freed from transmigration in the material existence.
