Answer

In Jain practice, it is generally better not to begin learning sacred sutras during an inauspicious or unsuitable time if your tradition considers 12am–1am as “kaal time.” For the first learning, recitation, or memorization of a sutra like the 12 Atichar Sutra, a calmer and more respectful time is preferred.

Explanation

A few important points:

• If your sampradaya or guru says that this time is prohibited, then follow that guidance.
• If there is no specific rule in your lineage, Jain Dharma does not usually treat every hour of the night as universally forbidden for all study, but sacred learning is still ideally done at a proper, pure, and शांत time.
• For scriptural study, the best time is usually when the mind is:

- calm - alert - respectful - free from sleepiness or distraction

So, if 12am–1am is considered unsuitable in your home or tradition, it is better to wait and learn it at a better time.

Spiritual Understanding

In Jain Dharma, the spirit of learning matters deeply. Sutras are not ordinary text; they are to be approached with:

• reverence
• purity of mind
• proper intention
• discipline

That is why many Jain families and teachers prefer study during auspicious and attentive hours rather than late-night hours.

Takeaway

Best practice: learn the 12 Atichar Sutra at a more suitable time, not during 12am–1am if that period is regarded as kaal time in your tradition. Simple rule: when in doubt, choose a respectful and calm time for sutra learning.
