तमेव शरणं गच्छ सर्वभावेन भारत।
तत्प्रसादात्परां शान्तिं स्थानं प्राप्स्यसि शाश्वतम्।।18.62।।

This empirical statement tat prasadat means by His Grace. It should be understood that Lord Krishna is referring to His Grace as that of any of His avatars or incarnations and expansions as authorised in Vedic scriptures. They all as a part of Lord Krishna abide as paramatma the supreme soul within the heart of all jivas or embodied beings. Any part of the whole is imbued with the whole. So Lord Krishnas three aspects of the brahman the spiritual substratum pervading all existence, paramatma and bhagavan which is His original eternal two armed spiritual form which includes all of His avatars in many different forms. So this verse should be understood empirically as well. Clarifying this point further an example is given from Mahabharata that states: Dronam prati Bhima vacanavat which means: Bhima said that Drona was a father to Him. Bhimas actual father was King Pandu but he spoke empirically to illustrate that the affection he received from Drona was like from a father. This is the gist of it.
