In Jainism, the timing for reciting sutras (scriptures) is guided by the principle of minimizing himsa (violence), especially towards microscopic beings that are more active during the night and early morning. According to traditional Jain practice:

For Shwetambar Jains: Sutra recitation and religious activities such as pratikraman, samayik, and puja should ideally begin at least 48 minutes after sunrise (this period is called "Ratrisheṣa" or "Gaudhuli Bela" has ended). This is to ensure that activities do not harm the subtle life forms present in abundance during dawn and dusk.

For Digambar Jains: The practice is similar, and they generally wait until after sunrise, but specific timings may vary by sect or tradition, usually at least 48 minutes after sunrise.

Summary: You should start to recite sutras at least 48 minutes after sunrise according to most Jain traditions. However, some may wait up to 1 hour after sunrise, depending on local customs and the guidance of Jain monks or scholars.

For precise timing and observance, always consult your local Jain community or spiritual teacher.
