According to Theravada Buddhism:
1.How does Decisive Supporting Cause (Upanissaya Paccaya) work? For example, when Venerable arahant Anuruddha asked Sangha what to do to attain divine-eye in Lord Padumuttara Buddha's dispensation, why did Sangha tell him to offer light to Buddha's stupa instead of practising kasina meditation? Did that offering become a supporting cause for him to attain divine eye? If yes, how? Aren't sensual wholesome kamma and fine-material (rupavacara) kamma different and unrelated?
2.Similarly, Venerable arahant Panchadeepadaika (Apadana pali - Bhikkuni apadana, 15th apadana) says that she became proficient in samadhi and dibba-caccu abhinna (divine-eye) as a result of offering 5 lamps to Lord Padumuttara Buddha's bodhi tree. She must not have practised kasina because she was born in the second deva realm in the subsequent life. How did this happen? Does the results of light-offering kamma give you the ability (such as a clear mind) to succeed in kasina meditation therefore attain samadhi and abhinna?
3.Also, Venerable arahant Pilindawachcha (Apadana pali - Bhikku apadana, 391st apadana) says that he obtained a great wisdom power as a result of offering knives, needles, razors and fragrance to Lord Padumuttara Buddha and Sangha. Can you please explain how offering can increase wisdom through Upanissaya Paccaya? I thought wisdom can only be developed through meditation.
4.I think my samadhi and wisdom faculty, out of five faculties, are very weak. If I made an offering to Buddha (such as light, fragrance) and Sangha and make a wish that in future lives, I get the ability to attain all 8 jhanas and abhinna quickly in one sitting and to develop vipassana meditation quickly and deeply, would such a wish become true? Can that kamma develop my five faculties so that I become proficient in meditation in future lives and attain nirvana?
Thank you. May the Triple Gem Bless you all!
