Notes:

1. See, “Kamma, Saṅkhāra, and Abhisaṅkhāra – What Is “Intention”?.” Akusala kamma are the same as apuññābhisaṅ­khāra (apuñña abhisaṅ­khāra.)

2. The realms and the lifetimes are extracted from various suttā: see, for example, “Dhammacakkappavattana Sutta Interpretation – Uddesa, Niddesa, Paṭiniddesa”, WebLink: suttacentral: Saṅkhārupapatti Sutta (MN 120), and “Paṭhama Mettā Sutta (AN 4.125).”

▪In particular, WebLink: suttacentral: Sāleyyaka Sutta (MN 41) discusses how different types of kamma lead to rebirth among the 31 realms.

▪The “WebLink: suttacentral: Visākhā Sutta (AN 8.43)” gives lifetimes of various deva realms.

3. Tihetuka means kusala kamma done with alobha, amoha, and amoha.

▪Dvihetuka means kusala kamma done with alobha/amoha or adosa/amoha. They have not removed all ten types of micchā diṭṭhi but may have removed many. They grasp the new bhava without fully understanding, i.e., javana citta at the cuti-paṭisandhi moment will have “weak javana power.”

▪In contrast, one with tihetuka birth grasps the new existence with a full understanding of the laws of kamma. Therefore, amoha means removal of the ten types of micchā diṭṭhi.

▪Ahetuka births occur purely as a vipāka of a good kamma but without generating any javana citta. They have not removed most of the ten types of micchā diṭṭhi. Thus, “ahetuka” does not mean “without hetu” there. It just means an “unfortunate birth.”

▪See, “Paṭisandhi Citta – How the Next Life is Determined According to Gathi” for details.

4. CE = Celestial Years; M HY = Millions of Human Years.

5. A Mahā Kappa is the time for the Solar system to go through a complete cycle. A quarter of this (or an Asaṅkheyya Kappa or 20 kappa) is the life of the Earth or the Solar system. The solar system is born, destroyed, and reborn like living beings. See, “Buddhism and Evolution – Aggañña Sutta (DN 27).” The Buddha describes the length of one kappa in the “WebLink: suttacentral: Pabbata Sutta (SN 15.5).” The lifetimes of many realms given in Ref. 9; in the English translation, the lifetimes can be found in section WebLink: suttacentral: 18.6.2. Age Limit.

6. The connection between various jhānic states and the corresponding Brahma realms in, “WebLink: accesstoinsight.org: The Thirty-one Planes of Existence.”

7. The names of the four arūpa realms are descriptive of their characteristics.

▪Akāsānancāyatana comes from “ākāsa” + “ananta” or infinite + “āyatana,” or the realm where the infinite space is the focus of the mind (ārammaṇa).

▪Vinnānancāyatana comes from “viññāṇa” + “ananta” or infinite + “āyatana,” or the realm where the infinite viññāṇa is the focus of the mind (ārammaṇa).

▪Ākincannayatana comes from “ākin” + “ca” or mind + “āyatana,” or the realm where the focus of the mind (ārammaṇa) is only the mind.

▪Neva saññā nā saññā comes from “na” or not + “asañña” or without perception + “nā,” or not + “saññā” or perception, i.e., the realm where one cannot say whether there is either “no perception” or “there is perception.” One could go on for a short time without perception (just like in the asañña realm), but it comes back since the “bhava” is still there.
