Jainism ke anusar, samayik ek vishesh dharmik kriya hai jisme shuddhata aur ekagrata ka vishesh mahatva hai. Samayik karte samay vyakti ko shuddh, saaf aur sadharan vastra pehnane chahiye. Puja ke vastra (jo ki bahut alankrit ya bhari ho sakte hain) samayik ke liye uchit nahi maane jaate. Jain achar (conduct) ke anusar, samayik ke samay sadharan, saaf aur safed vastra (yathashakti) pehna uchit hai, taki man aur sharir dono shuddh rahe aur vyakti dhyan laga sake.

Isliye, puja ke vastra mein samayik nahi karna chahiye. Hamesha sadharan aur shuddh vastra pehn kar hi samayik karein.
