साधिभूताधिदैवं मां साधियज्ञं च ये विदुः। प्रयाणकालेऽपि च मां ते विदुर्युक्तचेतसः ॥

sādhibhūtādhidaivaṁ māṁ sādhiyajñaṁ cha ye viduḥ prayāṇa-kāle ’pi cha māṁ te vidur yukta-chetasaḥ

They who know Me as the knowledge of the elements, as that of the Shining Ones, and as that of the Sacrifice, they harmonised in mind, know Me verily even in the time of forthgoing.

In plain words: Krishna says those who know him as the truth behind the physical world, the gods, and sacred offering keep a steady mind. They know him even at the moment of death.
