Impermanence

[3][4] Impermanence, called anicca (Pāli) or anitya (Sanskrit), appears extensively in the Pali Canon[1] as one of the essential doctrines of Buddhism.

[1] All temporal things, whether material or mental, are compounded objects in a continuous change of condition, subject to decline and destruction.

This teaching serves as a foundational philosophy in Hinduism, encouraging detachment from material concerns and an understanding of the true, eternal self.

This insight is pivotal for Arjuna, as it reorients his perspective from the battlefield's immediate concerns to the broader, spiritual dimensions of existence, urging him to perform his duty without attachment to the outcomes.

[7] Even in the details of their respective impermanence theories, state Frank Hoffman and Deegalle Mahinda, Buddhist and Hindu traditions differ.

[10] Impermanence first appears in Greek philosophy in the writings of Heraclitus and his doctrine of panta rhei (everything flows).

This, along with his cryptic utterance that "all entities come to be in accordance with this Logos" (literally, "word", "reason", or "account") has been the subject of numerous interpretations.

... for at the moment that the observer approaches, then they become other ... so that you cannot get any further in knowing their nature or state .... but if that which knows and that which is known exist ever ... then I do not think they can resemble a process or flux ....Several famous Roman Latin sayings are about impermanence, including Omnia mutantur, Sic transit gloria mundi, and Tempora mutantur.
