Jainism ke anusar, "sagaropam" ek bahut bada samay ka maan hai jo Jain cosmology mein prayukt hota hai. Ek sagaropam (या सागरोपम) samay ka wo maan hai, jo ek samudra (सागर) ke bharne ya khali hone mein lagta hai, ek vishesh kalpanik tarike se.

Paribhasha (Definition): Ek sagaropam samay ko is prakar vyakhya kiya gaya hai:

• Ek 1 yojan lamba, 1 yojan chauda, aur 1 yojan gahra khadda hai.
• Usmein ek baar ek til (sesame seed) daala jaata hai har 100 saal mein.
• Jab tak wo khadda poora bhar nahi jaata, tab tak jitna samay lagega, use ek sagaropam kehte hain.

Samay ki drishti se:

• Jain granthon ke anusar, ek sagaropam lagbhag 10^15 (10 quadrillion) varshon ke aaspaas ka hota hai, lekin iski sahi ganana alag-alag granthon mein bhinn milti hai.
• Ye samaymaan itna bada hai ki maanav samay ke anusaar uska maan karna kathin hai.

Upyog: Sagaropam ka prayog mundan (immense) samayon jaise chakkar, ara, tirthankar ki umra, etc. ke sandarbh mein kiya jaata hai.

Saaransh: Ek sagaropam ek kalpanik parantu atyanth durlabh aur bahut bada samay ka maan hai, jo anant/amar samayon ko darshane ke liye Jain dharm mein diya gaya hai.
