THE SCIENCE OF THE CYCLES

"It has become customary to speak of Time as a passing sequence of events. A new and more correct view of Time becomes possible when man takes the steps to align himself with his higher Self. This achieved, the way is opened for a truer understanding of cyclic activity and non-activity, and thus of Time.

A Yuga Cycle (a.k.a. chatur yuga, maha yuga, etc.) is a cyclic age (epoch) in Hindu cosmology. Each cycle lasts for 4,320,000 years (12,000 divine years[a]) and repeats four yugas (world ages): Krita (Satya) Yuga, Treta Yuga, Dvapara Yuga, and Kali Yuga.
As a Yuga Cycle progresses through the four yugas, each yuga's length and humanity's general moral and physical state within each yuga decrease by one-fourth. Kali Yuga, which lasts for 432,000 years, is believed to have started in 3102 BCE. Near the end of Kali Yuga, when virtues are at their worst, a cataclysm and a re-establishment of dharma occur to usher in the next cycle's Krita (Satya) Yuga, prophesied to occur by Kalki.
There are 71 Yuga Cycles in a manvantara (age of Manu) and 1,000 Yuga Cycles in a kalpa (day of Brahma).

There are 71 Yuga Cycles (306,720,000 years) in a manvantara, a period ruled by Manu, who is the progenitor of mankind

100 years of Brahma.
A maha-kalpa (life of Brahma) lasts for 100 360-day years of Brahma, which lasts for 72,000,000 Yuga Cycles (311.04 trillion years) and is followed by a maha-pralaya (full dissolution) of equal length.

There are 1,000 Yuga Cycles (4,320,000,000 years) in a kalpa, a period that is a day (12-hour day proper) of Brahma, who is the creator of the planets and first living entities. There are 14 manvantaras (4,294,080,000 years) in a kalpa with a remainder of 25,920,000 years assigned to 15 manvantara-sandhyas (junctures), each the length of a Satya Yuga (1,728,000 years). A kalpa is followed by a pralaya (night or partial dissolution) of equal length forming a full day (24-hour day).

One day out of this long life of Brahma is called Kalpa; and a Kalpa is that portion of time which intervenes between one conjunction of all the planets on the horizon of Lanka, at the first point of Aries, and a subsequent similar conjunction. A Kalpa embraces the reign of 14 Manus, and their sandhies (intervals); each Manu lying between two sandhies. Every Manu's rule contains 71 Maha Yugas, - each Maha Yuga consits of 4 Yugas, viz., Krita, Treta, Dwapara, and Kali; and the length of each of these 4 Yuga is respectively as the numbers, 4, 3, 2 and 1.
The number of sidereal years embraced in the forgoing different periods are as follows:

360 days of mortals make a year
1 year
Krita Yuga contains
1,728,000 years
Treta Yuga contains
1,296,000 years
Dwapara Yuga contains
864,000 years
Kali Yuga contains
432,000 years
The total of the said 4 Yugas constitute a Maha Yuga
4,320,000 years
71 of such Maha Yugas form the period of the reign of 1 Manu
306,720,000 years
The reign of 14 Manus embraces the duration of 994 Maha Yugas which equal to
4,294,080,000 years
Add Sandhis, i.e., intervals between the reign of each Manu, which amount to 6 Maha Yugas, equal to
25,920,000 years
The total of these reigns and interregnums of 14 Manus, is 1,000 Maha Yugas, which constitute a Kalpa i.e., one day of Brahma, equal to
4,320,000,000 years
As Brahma's night is of equal duration, one day and night of Brahma will contain
8,640,000,000 years
360 of such days and nights make one year of Brahma, eqaul to
3,110,400,000,000 years
100 of such years constitute the whole period of Brahma's age, i.e., Maha Kalpa
311,040,000,000,000

A maha-kalpa (life of Brahma) lasts for 100 360-day years of Brahma, which lasts for 72,000,000 Yuga Cycles (311.04 trillion years) and is followed by a maha-pralaya (full dissolution) of equal length.

MAHA KALPA

LIFE OF BRAHMA

Krita Yuga contains 1,728,000 years

Satya Yuga (a.k.a. Krita Yuga), in Hinduism, is the first and best of the four yugas (world ages) in a Yuga Cycle, preceded by Kali Yuga of the previous cycle and followed by Treta Yuga. Satya Yuga lasts for 1,728,000 years (4,800 divine years).

Satya Yuga is known as the age of truth, when humanity is governed by gods, and every manifestation or work is close to the purest ideal and humanity will allow intrinsic goodness to rule supreme. It is sometimes referred to as the "Golden Age". Dharma (depicted in the form of a bull) symbolizes morality and stood on all four legs during this period; the legs of Dharma reduce by one in each yuga that follows. As per Bhagavata Purana, the four legs of Dharma are Tapas lit. 'austerity', Śauca lit. 'cleanliness' (or Dāna lit. 'charity'), Dayā lit. 'compassion' and Satya lit. 'truth'.

Treta Yuga in Hinduism, is the second and second-best of the four yugas (world ages) in a Yuga Cycle, preceded by Krita (Satya) Yuga and followed by Dvapara Yuga. Treta Yuga lasts for 1,296,000 years (3,600 divine years).

Treta means 'a collection of three things' in Sanskrit, and is so called because during the Treta Yuga, there were three Avatars of Vishnu that were seen: the fifth, sixth and seventh incarnations as Vamana, Parashurama and Rama, respectively.[citation needed. The bull of Dharma symbolizes that morality stood on three legs during this period. It had all four legs in the Satya Yuga and two in the succeeding Dvapara Yuga. Currently, in the immoral age of Kali, it stands on one leg.

Dwapara Yuga contains 864,000 years
Dvapara Yuga in Hinduism, is the third and third-best of the four yugas (world ages) in a Yuga Cycle, preceded by Treta Yuga and followed by Kali Yuga. Dvapara Yuga lasts for 864,000 years (2,400 divine years).

According to the Puranas, this yuga ended when Krishna returned to his eternal abode of Vaikuntha. There are only two pillars of religion during the Dvapara Yuga: compassion and truthfulness. Vishnu assumes the colour yellow and the Vedas are categorized into four parts: Rig Veda, Sama Veda, Yajur Veda and Atharva Veda.

Kali Yuga contains 432,000 years
Kali Yuga is the fourth, shortest, and worst of the four yugas (world ages) in a Yuga cycle, preceded by Dvapara Yuga and followed by the next cycle's Krita (Satya) Yuga. It is believed to be the present age, which is full of conflict and sin.

According to Puranic sources Krishna's death marked the end of Dvapara Yuga and the start of Kali Yuga, which is dated to 17/18 February 3102 BCE. Lasting for 432,000 years (1,200 divine years), Kali Yuga began 5,126 years ago and has 426,874 years left as of 2025 CE. Kali Yuga will end in the year 428,899 CE.

Near the end of Kali Yuga, when virtues are at their worst, a cataclysm and a re-establishment of dharma occur to usher in the next cycle's Krita (Satya) Yuga, prophesied to occur by Kalki.

MANVANTARA

AGE OF MANU

The term maha-manvantara refers to the evolution the whole universe through the "Great Age", which lasts for a maha-kalpa.
Maha-manvantara = Age of Brahma = 100 years of Brahma = Maha-Kalpa

The Maha-Kalpa embraces the whole lifetime of Brahmā, which is of 100 years (1 year are 12 of his months, which consist of 30 days each). For this reason it is called the "Age of Brahmā".

AGE OF BRAHMA

100 YEARS OF BRAHMA

Pralaya is a Sanskrit word that means "dissolution" or "melting away" (from laya: "to dissolve" and pra "away"). In Hinduism, it refers to a period where the universe is in a state of non-existence, which happens when the three gunas or qualities of matter are in perfect balance. H. P. Blavatsky defined it as, "A period of obscuration or repose - planetary, cosmic or universal--the opposite of Manvantara."
