Paryushan Parv is a highly sacred Jain festival observed by both Digambar and Shwetambar communities. Here’s a simple, clear overview:

• When it happens: It lasts for 8 days in Digambar tradition and 10 days in Shwetambar tradition. The dates vary each year according to the Jain lunar calendar.
• Main focuses: Intense spiritual practices such as fasting or partial fasting, confession of past misdeeds (Pratikraman), daily prayers, sacred study, and vows of self-discipline (shravan, upvas, or extended ekasan).
• Key practices common to both traditions:

- Samayik: a short meditation and reflection on right conduct. - Pratikraman: a solemn confession and repentance for faults committed during the period. - Five avas: ahimsa (non-violence), satya (truth), asteya (non-stealing), brahmacharya (chastity), aparigraha (non-attachment). - Reading or listening to Jain scriptures, and charitable acts or seva.

• Differences between Digambar and Shwetambar:

- Duration: 8 days (Digambar) vs 10 days (Shwetambar). - Observance details may vary in rites, scriptures read, and specific prayers.

• End of Paryushan: The period typically culminates with forgiveness (Kshama or Kshamapana) where people seek and grant forgiveness to each other.

About the phrase “Anu hard”: in standard Jain practice there isn’t a well-known rite or term exactly named “Anu hard.” It might be a shorthand or a mis-spelling of a related term (for example, Anuvrat, Anushasana, or Anuhaar in some local usages). If you can share a bit more context or the exact word/script you saw, I can explain precisely what it refers to within Jainism.
