Words of wisdom

"Infinity multiplied, divided, subtracted and added by infinity is infinity. Infinity is infinite, an endless thing, so the universe is also an endless thing in which we are nothing; we are not even an atom or an electron or proton." - Brihadaranyaka upanishad

Pre school classes on astrology

Well this is from a pre school level book that i am reading on astrology.

The Zodiac or Rasi Chakra is defined as a belt of the celestial sphere extending 9 degrees of the ecliptic (the apparent orbit path of the sun around the earth in a geo-centric scheme).

The movement of the Sun through the Zodiac comprises the month (Masa) and the point of time of sun’s entry is known as Sankramana.

The most basic and universal unit of time is the day or Dina, which extends to 24 hours. Multiples of these give us weeks, months and years. A day can be further divided into hours which in Indian astrology is Hora, and is equivalent to an hour which are ruled by the planets in the following order: Arka, Shukra, Budha, Chandra, Manda, Jeevo, Dharasuta Sun, Venus, Mercury, Moon, Saturn, Jupiter and Mars rule each hora in a cyclic order, which repeats itself.

A day comprises three cycles of seven horas each, plus three hora of the next cycle. According to Hindu astrology, a day always start at sunrise. For example - Sunday begins with the cycle sun, Venus at sunrise and after completing three cycles, the three hours left would be Sun, Venus, and Mercury. The next day starts with the fourth hora of the cycle, which is ruled by Moon, and hence the day is called Monday. Thus each day of the week is named after the planet ruling the first hora of that day at sunrise. A week, consisting of seven days, named after the planets is called Varam.

Apart from the 12 solar months, there are 12 lunar months called Masas named after the Nakshatra (star) in which the full moon occurs in each successive month.

The year, known as Samvatsara, has two sections of six months each known as Ayanas. The Northern declination of the Sun, when it appears to move between the signs of Makara and Mithuna is called Uttarayana. The southern declination when the sun appears to move between Kataka and Dhanus is called Dakshinayana.

A year is further divided into six seasons known as Ritus. The Seasons Two months of the year form one season.

A solar day starts from sunrise till next sunrise. A lunar day, known as the Thithi is calculated from the longitudinal distance between the sun and moon. There are 30 Thithis in a lunar month distributed over 360 degrees, thus each Thithi has a span of 12 degrees. There are 14 Thithis in the Shukla Paksha and 14 Thithis in the darker half with Pournamy and Amavasya being the other 2 days of the month.

Most of the above are more like a trivia to me. I started studying the basics and just got lost without a teacher. May be someday i will find a guru to learn.

Panchangam

The Indian almanac is known as the Panchangam, which means ‘having five limbs.’

The pachangam gives information regarding the basic divisions of time according to ancient hindu traditions. These are the Thithi (phase of the moon), Vara (day of the week), Nakshatra (star or constellation through which the moon is passing), Yoga (a sensitive point in the zodiac derived by adding the longitudes of the Moon, the Sun and a constant which is 930 20’) and Karana (half a Thithi).

In addition, the Panchanga gives tables for the correction of the time of sunrise of longitudes, the time taken by the sun to traverse each Rasi (zodiac sign), the Navamsa (9th Division) chart, the Shadvarga (6 major division) chart, the Sayana (tropical) position of the planets based on Driganitha (astronomical data) and so on. The basic information is according to the Siddhantas (astronomical and mathematical treatises) with corrections made accounting for the Ayanamsa (precession) for the year.

The Hindu concept of time is divided into four eras (Yugas). Krita, Treta, Dwapara and Kali yugas. The Hindu astronomers assume the planets to be in a line of mean conjunction with the first point of Aries at the beginning of a Maha Yuga. The planets would come back to their initial relative positions the end of Revati (Zeta Piscium) and the beginning of Ashwini at the beginning of the next Maha Yuga, at a place on the equator 76 degrees East of Greenwich.

They calculated the period of a Maha Yuga as 4,320,000 years. Currently, we are in Kali Yuga into its 52nd century.

Maha Yuga is made up of 12,000 Deva Samvastara (years of devas) or 4,320,000 ordinary years. 71 Maha Yugas constitute one Manvantara (308,448,000 years). 14 Manvantaras or Manus make up one Kalpa or Brahma Dina. The end of each Manvantara is said to bring about changes in the earth’s gravity and other visible changes in the Universe.

We do the the Sankalpam mentioning that we are in the 7th Manvantara in which 27 Maha Yugas have passed. We are now in the last Yuga (Kali Yuga) of the 28th Maha Yuga. We are still in the beginning of Kali Yuga with 4,26,939 years yet to elapse before it ends.

The fact that the rishis (seers) could conceive of such vast stretches of time speak of their scientific brilliance. The Vedas are a storehouse of scientific and rational knowledge and also supra-scientific knowledge (Gnana).
