The human mind constantly tries to grasp the greatness of God, only to meet an infinite reality that goes far beyond its limits. There is an overwhelming sense of wonder when realizing the sheer volume of God's thoughts and miracles. These wonders accompany a person endlessly, forming a deep spiritual connection that remains unbroken through the passage of time, whether one is asleep or awake.
The primary approach among commentators is that it is simply impossible to count or measure these divine thoughts. If anyone were to try, they would find that God's wonders outnumber the grains of sand by the sea [רד״ק, אבן עזרא, מצודת דוד, מאירי, ביאור שטיינזלץ]. However, other perspectives suggest that this vast, uncountable number actually refers to the good deeds of the righteous [רש״י, תורה תמימה]. This idea carries a powerful lesson: just as a small amount of sand acts as a barrier protecting the dry land from the crashing sea, the massive accumulation of righteous deeds serves to protect the entire world [תורה תמימה]. Taking a completely different angle, another interpretation suggests the comparison is not to grains of sand at all, but rather to the legendary phoenix, a creature that lives on and never truly dies [אלשיך].
The experience of waking up and finding oneself still in the presence of God is understood on several different levels. On a personal level, it describes a state of constant devotion. A person can be so deeply immersed in thoughts of God during the day that they dream about Him at night. The moment they open their eyes, they immediately feel close to God, surrounded once again by His miracles [רד״ק, ביאור שטיינזלץ]. Adding a mystical layer to this, the nighttime experience can be seen as a prophetic vision where the human soul connects with the divine. Upon waking, the person realizes this was no ordinary dream, but a deep spiritual encounter that leaves them lingering in God's presence [אבן עזרא].
Another way to understand this endless connection is through the lens of human limitation. The idea serves as a theoretical exaggeration to show how impossible it is to fully comprehend God. Even if a person were to give up sleep entirely, stay awake their entire life, leave behind all earthly troubles, and exist solely with God like an angel in heaven, they would still never finish counting His greatness [אבן עזרא, מצודת דוד, מאירי].
Finally, this ongoing presence takes on historical and future meanings. The act of waking up can symbolize the ultimate resurrection, where humanity will rise from the dust to live eternally with God, never to face death again [אלשיך]. Alternatively, it reflects the enduring loyalty of the Israelites throughout history. The nation declares that even as the end of their allotted generations approaches, they remain completely devoted to the fear of God, never turning away from Him [רש״י].
