इन्द्रियार्थेषु वैराग्यमनहङ्कार एव च।जन्ममृत्युजराव्याधिदुःखदोषानुदर्शनम्॥
indriyārtheṣu vairāgyam anahankāra eva cajanma-mṛtyu-jarā-vyādhi-duḥkha-doṣānudarśanam
Word by word
The verse says
— not clinging to what the senses want; no sense of being someone in particular; seeing clearly the trouble and the fault in birth, in age, in illness, in pain —
In plain words
One item here is uncomfortable and it is the last.
Seeing the difficulty in birth, ageing, illness, pain. Not ignoring it. Not making peace with it. Looking straight at it.
The word is anudarśanam — keeping it in view.
Where you've felt this · in growing older
Your grandmother says, plainly, that she cannot manage the stairs any more and that it is annoying. She does not make a speech about it. She also does not pretend it is temporary. The sentence takes four seconds and then she talks about something else.
Going deeper
Keeping difficulty in view is listed as knowledge, which cuts against a great deal of what passes for positive thinking.
The instruction is not to dwell. Anudarśanam means seeing along, keeping something in sight while you go about things. What is to be kept in sight is unpleasant and entirely factual: bodies are born, age, fall ill and hurt.
Most strategies for dealing with that involve not looking. The verse lists looking as a kind of understanding.
And there is a practical reason, visible in anybody who has managed it. People who have genuinely taken in that this is how it goes tend to be easier to be around, not harder. The energy that was going into not noticing becomes available for something else, which is why this sits in a list that began with patience and the absence of display.
