His Master's Toys

“All is but toys: renown, and grace, is dead; The wine of life is drawn, and the mere lees Is left this vault to brag of” --- William Shakespeare

Concept of Time in Hindu Mythology

I love this: “We now move on from the human plane to the world of the departed souls – the pitrus. Here, a human month equals the length of a day. The brighter half of a lunar month constitutes the pitru’s day time and the darker half their night. ”

I also love this: “Thus, a single day in Bhrahma’s life spans 2000 * 4,320,000 ie. 8,640,000,000 human years. 360 such days, each lasting 8.6 billion years constitute a year in Bhrahma’s life, which lasts for a 100 Bhrahma years. At the end of one Bhrahma’s life, another starts. This cycle goes on and on.”

Concept of Time in Hindu Mythology

The smallest unit of time is a kaashta which is 18 times the amount of time it takes to blink an eyelid. 10 kaashtas make a kshanam and 12 kshanams constitute a muhoortam. 60 of these muhoortams constitute a day.

30 days constitute a month and 3 months make up a ritu. 12 months of course constitue a human year.

We now move on from the human plane to the world of the departed souls – the pitrus. Here, a human month equals the length of a day. The brighter half of a lunar month constitutes the pitru’s day time and the darker half their night.

In the realm of the Devas or the Gods, a human year constitutes a single day. The brighter half of the year Uttarayanam makes up the day time hours of the Devas while the darker half Dakshinayanam makes up the night time hours.

An epoch or a yuga is the next higher level of measurement. 1200 Deva years constitute the Kaliyuga or the present epoch that we are believed to be living in; 2400 deva years make up the Dwapara yuga that preceded kali yuga; 3600 years made up the Treta yuga and 4800 the Krita yuga respectively.

Thus, the length of the Kaliyuga is 1200*360 i.e. 432,000 human years. A cycle of 4 yugas is referred to as the catur yugas. A cycle of catur yugas lasts for 12,000 deva years or 12,000* 360 i.e. 4,320,000 human years.

How do these time measurements correlate with the process of creation?

Bhrahma in Indian mythology is referred to as the creator. A thousand catur yugas are said to make up the daylight hours of a single day of Bhrahma’s life. Another thousand make up the night time of a single day of Bhrahma. Thus, a single day in Bhrahma’s life spans 2000 * 4,320,000 ie. 8,640,000,000 human years.

360 such days, each lasting 8.6 billion years constitute a year in Bhrahma’s life, which lasts for a 100 Bhrahma years. At the end of one Bhrahma’s life, another starts. This cycle goes on and on.

A Bhrahma’s life is also known as a Para. Each half param is referred to as a parardham. It is believed that we are currently living in the 2nd half of the life of the present Bhrahma.

It is to be noted that in the performance of Vedic rituals, the frame of time in which the ritual is being performed is specified both in macro and in micro terms, the term ‘dviteeya paraardhe’ (the second half of Bhrahma’s term) is stated.

The reference point here is the moment of commencement of creation of the Universe by Bhrahma.

When we say ‘dviteeya paraardhe’, which Bhrahma are we referring to? How many Bhrahmas have preceded the current one? This specification is non existant in vedic mantras. Since the whole process is cyclical, with one Bhrahma commencing when another completes, and with this process repeating forever, there may not be any significance in stating the position of Bhrahma.

In a cyclical concept of time every starting point will have to be an ending point. If time is postulated as being linear and unidirectional there will have to be an absolute starting point for time.

This cyclical nature of time as believed in Indian mythology refers to time as ‘anaadi’ or that without a beginning.

Yet another measure of time is Kalpa. The puranas are named after kalpas; thus we have the matsya kalpa, koorma kalpa, lakshmi kalpa, sweta varaaha kalpa, shiva kalpa, bhrahma kalpa, vishnu kalpa and so on. Each Bhrahma’s term lasts for a period of 7 kalpas. The current period in time is said to belong to the sweta varaaha kalpam, which is in the second half of the life of Bhrahma.

A kalpam or an epoch is made up of 14 manvantaras and each manvantara spans 71 caturyugas. The fourteen manvantaras are respectively swayambhuva, sawosisha, audhama, thaamasa, raivatha, sakshusha, vaivasvata, savarni, daaksha savarni, bhramha savarni, dharma savarni, rudra savarni, rouchya and bowdhya. The present kaliyuga is the 28th in the present Vaivaswata manvantara.

Sankalpam: Thus, vedic mantras pin point the time of performance of a ritual – by narrowing down from dwiteeya paraardhe (in the 2nd half of the term of Bhrahma), Sweta varaaha kalpe (in the kalpa sweta varaaha), Vaivasvata manvantare (in the 7th manvantaram), Kaliyuge (in the kali epoch) – through the finer details such as the name of the current year, month etc.

Remotely programming a cardiac pacer or defibrillator

It is not important to ask ‘when’ the first heart device will be hacked. As is always with any innovation, universal acceptance happens sooner rather than later, however controversial it might be.A more interesting discussion is — what happens if the heart devices allowing open access. What is it that changes? 

As with every change, the outcome is at the minimum a duality and everything in between. If the at least, the opposite poles can be identified (at any particular instant — this is important), then it allows us to break down the problem into simpler blocks.

As an example — if a hundred cellphones are distributed in a village in Ethiopia — the two possible outcomes could be:a) A hyper-connected village, and a range of services / economic changes that emerge as a consequence.b) the cellphones are never used for productivity at all — they are used a jewelries instead.

The actual outcome would be a combination of the above opposites, of course.In that sense, if I try and analyze the outcome of an innovation such as a heart device with open api —

  •  positive: a range of middle layer services that promote life — such as: heart beat based art creator, romance analyzer (does her heart beat faster when she’s around me?), stress analyzer (during war?), longer life expectancy, music which modifies according to the heart rate (different music during sleep and jogging), better monitoring of food quality…. there is literally no end. 
  • negative: a range of possibilities that destroy life — such as: freaky weapons of mass destruction, employee exhaustion monitoring, mass scale deaths due to machine failures…

By tomorrow morning, I will think of fifty more possibilities. Of course, I am just ranting… early morning coffee induced rant. There is no point to this rant, since both of the above will happen sooner or later. The fact is, we are living a cyberpunk novel… we just don’t see it yet. ;)
