“Raas” can mean two different things in Jain context. Here are both, very simply:

1) Āra (काल का भाग) — the six time-periods in each half-cycle

• Sukhama‑Sukhama (most pleasant)
• Sukhama (pleasant)
• Sukhama‑Dukhama (mixed: more pleasant)
• Dukhama‑Sukhama (mixed: more sorrow)
• Dukhama (sorrowful) – our present era in Avasarpinī
• Dukhama‑Dukhama (most sorrowful)

These six āras are accepted across both Digambar and Śvetāmbara traditions. Short explanation: happiness steadily declines through the six in Avasarpinī, and increases in Utsarpinī. For a simple overview, see .

2) Rasa (रस) — the five tastes, a guṇa (quality) of pudgala (matter)

• Madhura (sweet)
• Amla (sour)
• Tikta (bitter)
• Kaṭuka (pungent/acrid)
• Kaṣāya (astringent)

Note: Jain doctrine lists five tastes. The popular “six tastes” belongs to Ayurveda and is not the Jain classification. This five‑rasa list is common to both Digambar and Śvetāmbara understandings based on Tattvārthasūtra explanations.

If by “raas” you meant one of the above, this should cover it.
