Conclusion

Here is how Lord Krishna concludes the discourse between him and Arjun.

Do as you wish after due deliberations on the most secret revelations from me.

इति ते ज्ञानमाख्यातं गुह्याद्‌गुह्यतरं मया ।
विमृश्यैतदशेषेण यथेच्छसि तथा कुरु ॥१८:६३॥

Lord Krishna says to Arjun:
Thus the most confidential of the confidential knowledge has been revealed to you by me. After due deliberations in its entirety, do as you wish.

(If you are still confused) Don't worry. Just take my refuge and I will liberate you from all sins.

सर्वधर्मान्परित्यज्य मामेकं शरणं व्रज ।
अहं त्वां सर्वपापेभ्यो मोक्षयिष्यामि मा शुच: ॥१८:६६॥

Lord Krishna says to Arjun:
(If you are still confused) Don't worry. Just come to my only refuge by abandoning all dharma (duties). I will absolve you of all the sins.

Arjun says his delusion has vanished and doubts gone. He is ready to do as Krishna says.

अर्जुन उवाच -
नष्टो मोहः स्मृतिर्लब्धा त्वत्प्रसादान्मयाच्युत ।
स्थितोऽस्मि गतसन्देहः करिष्ये वचनं तव ॥१८:७३॥

Arjun says to Lord Krishna:
The delusion is vanished, memory is gained by me with the grace from you, O infallible (O Krishna). I am standing with the doubts gone, will do as per your command.
