In step with our ancient scriptures, brahma, the creator, creates and destroys the universe cyclically. The lifestyles of brahma is 100 divine years called mahakalpa. Ordinary he creates 14 manus separately and they create and manage the world. So there are fourteen manus in a single divine day known as kalpa of brahma.

The lifestyles of every manu is called manvantara and it has 71 eras of four quarters. Each area is has 4 yugas - krita or satya, treta, dvapara and kali. The subsequent are the whole calculations of vedic devices of time and periods.

India has given the idea of the smallest and the largest measure of time.

Krati = 34,000th of a second

The time taken to tear apart the softest petals of a lotus is called 'TRUTI'

100 Trutis make 1 Lub

30 Lub make 1 Nimesh

27 Nimesh make 1 Guru Akshar

10 Guru Akshar Make 1 Pran

6 pran Vighatika make 1 Ghatika or Dand

60 Ghati make 1 day and night

That means, in a day and night, there are 17,49,60,000,00 Trutis

Thus, according to Western science, there are 86,400 seconds in a day and night, whereas in Indian science, a day and night consists of 17,49,60,000,00 Trutis.

According to another system, the division of time is

1 day or 24 hours = 60 Ghatis

1 Ghati = 60 Vighati (also called Pala or Kala)

1 Vighati = 60 Lipta or (also called Vipala or Vikala)

1 Lipta = 60 Vilipta

1 Vilipta = 60 Para

1 Para = 60 Tatpara

As a lot of charts made in the olden days mention the birth time in Ghatis and Vighatis the following is the conversion to remember:

5 Ghatis = 2 hours

5 Vighati = 2 minutes

Another system of time at micro level is

60 Tatparas = 1 Paras

60 Paras = 1 Vilipta

60 Vilipta = 1 Lipta

60 Lipta = 1 Ghatika (Dand)

60 Ghatika = 1 Day & Night)

Therefore, it is clear that there are 46,65,60,000,00 Tatparas in a day and night.

6.3. The Vedic Units of Time – Macro level

SATYUG 4,32,000 YEARS X 4 = 17,28,000 YEARS

TRETA 4,32,000 YEARS X 3 = 12,96,000 YEARS

DWAPAR 4,32,000 YEARS X 2 = 8,64,000 YEARS

KALIYUG 4,32,000 YEARS X 1 = 4,32,000 YEARS

1 MAHAYUG (GRAND TOTAL OF ALL THE YUGAS) = 4,320,000 YEARS

71 MAHAYUG = 43,20,000X71 = 1 MANVANTAR

1 MANVANTAR = 30,6720,000 YEARS

14 MANVANTAR = 4,294,080,000 YEARS

(There are 14 Manvantars)

The earth remains submerged in the water for the period of 8,64,000 years i.e. half the number of Satyug, before the start of each Manvantar, it also remains submerged in the water for the same number of years, i.e. 8,64,000 years, after the completion of each Manvantar.

So in 14 Manvantars the number of years

17,28,000 x 15 = 2,59,20,000

(Number of year in Satyug)

+ 14 Manvantar = 42,9, 40,80,000

1 Kalpa = 4320,000,000 years

One day & night of Brahma = 4,320,000 Mahayug x 100 = 4,320,00,000 years

Since the one moment in the life of Brahma is considered to be of our 100years, therefore the life of Brahma in 100 years will be

4,32,00,00,000 x 360 x 100 = 1,555,200,000,000 years

CREATION : The universe cyclically

The Present Age of Cosmos according to the Vedic System is as follows:

There are 14 Manvantaras altogether. The present period is passing through the seventh Manvantara called Vaivaswata Manvantara.

One Manvantara consists of 71 Mahayugs, out of which 27 Mahayugs have already passed. We are passing through the first phase of the Kali Yuga which itself is the third Yuga of the 28th Mahayuga and which has come after the passing of Satya Yuga, Treta and Dwapar Yuga.

The time period of Manvantara (exclusive period, when the earth is submerged in water, in the beginning and in the end) = 306,720,000 years..

1) Multiplying these years by 6 = 30,67,20,000 x 6 (Because we are in the midst of 7th Manvantara, of the Svetvaaraah Kalpa and 6 Manvantaras have already passed) = 1,8,0,300,000 years

The time period of Pralaya consists of 17,28,000 years since 7 Pralayas have passed, after the end of 6th Kalpa and before the beginning of 7th Kalpa, so 17,28,000x 7 = 12,096,000 years

Adding we have:

1,840,300,000 + 120 96 000 + 1,852,396,000 years

Therefore, after 1,85,24,16,000 years 'VAIVASVAT MANVANTARA' has started.

2) 27 Mahayugs with each Mahayuga consisting of 43,20,000 years. 43,20,000 x 27 = 116,640,000 years have passed

Total = 1,96,90,56,000 years

3) Now the time period of Kali Yuga in the 28th Yuga =

Time period of Satya Yuga = 17,28,000

Time period of Treta = 12,96,000

Time period of Dwapar = 8,64,000

TOTAL = 38,88,000

Since all the above three Yugas have already passed, it means that after 38,88,000 years, Kali Yuga came into existence.

4) Kali Yuga started on Bhadrapada, Krishnapaksha -13th day, in Vyatipaat yoga at midnight, in the Aashlesha Nakshatra and the age of the Kali Yuga has been fixed as 5101 years as till date that is Vikram Samvat 2057 = Shaka 1922 = 2000 AD.

Sum of all the three Yugs = the Sum of 27 Mahayugas and Manvantar + the time period of Kali Yuga till date.

Kalpa consist of 4,32,00,00,000 years and out of these 1,97,29,49,101 years have passed. Therefore, the earth's existence, according to the calculations devised by our ancient sages, comes up to 1,97,29,49,101 years till date. It is interesting to note that according to scientific calculations, the age of the cosmos is estimated between 15 and 20 billion years.
