In Jainism, time is divided into cycles called kalachakras, each of which is further divided into two halves: Utsarpini (ascending half-cycle) and Avasarpini (descending half-cycle). Each half-cycle consists of six periods known as aras.

The 2nd ara is called Sukhma-sukhma in Avasarpini (descending), or Dukhma-dukhma in Utsarpini (ascending).

Duration of the 2nd Ara: According to Jain scriptures, the duration of the 2nd ara in Avasarpini is 42,000 years.

Summary:

• 2nd Ara Name: Sukhma-sukhma (Avasarpini) / Dukhma-dukhma (Utsarpini)
• Duration: 42,000 years

This period is characterized by a gradual decline in happiness and lifespan compared to the first ara, but it is still considered a time of relative peace and prosperity.
