साधिभूताधिदैवं मां साधियज्ञं च ये विदुः।प्रयाणकालेऽपि च मां ते विदुर्युक्तचेतसः॥
sādhibhūtādhidaivaṃ māṃ sādhiyajñaṃ ca ye viduḥprayāṇa-kāle ’pi ca māṃ te vidur yukta-cetasaḥ
Word by word
The verse says
Those who know me as what stands behind matter, behind the gods, and behind sacrifice — they know me even at the hour of leaving, their minds joined to me.
In plain words
Three technical words in one line, and Krishna does not stop to explain any of them.
Arjuna will not let that pass. His first words in the next chapter are a list of exactly these terms with what do they mean attached.
The promise itself is simple. What is steady in you now is what is available at the end.
Where you've felt this · in study
In the last ten minutes of a hard exam, most people write faster and worse. The one who actually understood the subject tends to slow down. Pressure does not invent a new person under the desk. It shows you the one who was already sitting there.
Going deeper
The hour of leaving gets its first mention here, and the way it is handled sets the tone for everything said about it later.
There is no threat in the line. No warning about what becomes of people who get it wrong at the last moment. What is described is continuity. A mind that has been joined stays joined, and the final hour is not a separate examination with rules of its own.
That is the opposite of how this teaching often gets used. The end is not being set up as a trap for the unprepared, and anyone who has been frightened with it deserves to know that.
It also gives the practice its real justification. Nothing you can arrange in a final hour will be steadier than what you have been doing for years. The years are not preparation for a test at the end. The end is simply a reading of the years.
