Word “Haṁsachariya” (often written Haṁsācarya / Haṁsacharya) can be broken into two parts:

1. Haṁsa (हंस)

- Literal meaning: swan. - In Indian spiritual literature (including Jain usage in some commentaries), haṁsa is often a symbol of: - purity - detachment (moving on water but not wet) - the ability to “separate” good from bad (like the poetic idea of separating milk from water).

1. Carya / Chariya (चार्य / चर्या)

- From the root car – to move, to act, to live. - Meaning: conduct, way of living, spiritual practice, behaviour.

So purely as a word‑breakdown:

> Haṁsachariya = Haṁsa + Chariya > = “swan‑like conduct” or “conduct/practice like a haṁsa”

Spiritually, this usually implies:

• a life of purity,
• detached from worldly mud like a swan on water,
• with discriminating wisdom, choosing what is spiritually beneficial and leaving the rest.

I am not aware of “Haṁsachariya” as a fixed, technical name of a vow or formal practice in the main Jain scriptures; it is more an expressive compound whose pieces are as explained above.
