Kālattaya Sutta
First published: February 28, 2026
What you learn
This sutta teaches that all five aggregates (form, feeling, perception, formations, and consciousness) are impermanent across past, present, and future time periods. The Buddha emphasizes that recognizing this impermanence in all time frames leads to the cultivation of disenchantment, dispassion, and ultimately cessation.
Where it sits
This discourse belongs to the Khandha Samyutta's foundational teachings on the impermanent nature of the five aggregates, complementing other impermanence teachings such as SN 22.85 (Yamaka Sutta) and connecting to the broader framework of the three characteristics found throughout texts like SN 22.59 (Anattalakkhana Sutta).
Suggested use
Apply this teaching by examining your direct experience of the five aggregates across past, present, and future time frames. When noticing attachment to past experiences or anticipation of future states, recall the impermanence of these aggregates and focus your practice on developing disenchantment with present-moment aggregates as the most immediate path to dispassion and liberation.

- All five aggregates (form, feeling, perception, formations, consciousness) are impermanent across past, present, and future time periods
- Present-moment impermanence is even more evident than past or future impermanence
- Proper understanding leads to non-attachment to past aggregates and non-delight in future aggregates
- The practice goal is developing disenchantment, dispassion, and cessation regarding present aggregates
- This teaching applies equally to all five aggregates without exception
- Thinking that impermanence only applies to gross physical changes rather than the constant flux of all aggregate experience
- Believing that understanding impermanence intellectually is sufficient without developing actual disenchantment and dispassion
- Focusing only on past or future impermanence while missing the immediate reality of present-moment impermanence
- When experiencing attachment to past experiences, recall that those aggregates were impermanent and no longer exist
- When anticipating or craving future states, remember that future aggregates will also be impermanent and unreliable
- Observe present-moment arising and passing of bodily sensations, feelings, perceptions, mental formations, and consciousness
- Cultivate equanimity toward current aggregate experiences by recognizing their impermanent nature
