The Sanskrit term Āyādiṣaḍvarga can be transliterated into English as Ayadisadvarga or Ayadishadvarga, using the IAST transliteration scheme (?).
Āyādiṣaḍvarga (आयादिषड्वर्ग).—Yet another important conceptual instrument that is employed in the actualization of pramāṇa is āyādi-ṣaḍvarga, the set of six “operating principles” or “significations” that are proper to the “science” of astrology. The insistence, rather, is on their application in architectural and iconographic measurement. Their application is intended to “verify” the measurements of the architectural and iconographic object against the dictates of astrology that lay out the conditions of auspiciousness.
The particular āya, vyaya, ṛkṣa, yoni, vāra, and tithi or aṃśa of all architectural and iconographic objects (settlement, building, image) must be calculated and ascertained. This process is based on the principle of the remainder. An arithmetical formula to be used in each case is stipulated, which engages one of the basic dimensions of the object (breadth, length, or perimeter/circumference).
The set of formulae are as follows (Mānasāra IX, 63-73):
- Āya is the remainder of 8/12 times the length.
- Vyaya is the remainder of 9/10 times the breadth.
- Ṛkṣa is the remainder of 8/27 times the length.
- Yoni is the remainder of 3/8 times the breadth.
- Vāra is the remainder of 917 times the perimeter (or circumference).
- Tithi is the remainder of 9/30 times the perimeter.
- (6a) Aṃśa is the remainder of 4/9 times the perimeter.
Vastushastra (वास्तुशास्त्र, vāstuśāstra) refers to the ancient Indian science (shastra) of architecture (vastu), dealing with topics such architecture, sculpture, town-building, fort building and various other constructions. Vastu also deals with the philosophy of the architectural relation with the cosmic universe.
Jyotisha (astronomy and astrology)
Āyādiṣaḍvarga (आयादिषड्वर्ग).—Yet another important conceptual instrument that is employed in the actualization of pramāṇa is āyādi-ṣaḍvarga, the set of six “operating principles” or “significations” that are proper to the “science” of astrology. These significations, which may be seen as constituting the “horoscope” of an architectural or iconographic object, are:
- āya, “income”, having twelve “fruits” (that is, effects);
- vyaya, “expenditure”, having ten fruits;
- ṛkṣa (also mentioned as nakṣatra and kṣapa), “planet”, twenty-seven in number;
- yoni, “source”, eight innumber;
- vāra, “solar day”, seven innumber;
- tithi, “lunar day”, thirty innumber.
Sometimes, aṃśa, literally, “part, division”, nine in number, is mentioned in place of tithi as the sixth principle to be applied. The Mānasāra takes for granted that these astrological significations are familiar to its audience and therefore does not treat them comprehensively and systematically in one place.(Source): McGill: The architectural theory of the Mānasāra (astrology)
Jyotiṣa (ज्योतिष, jyotisha or jyotish) basically refers to ‘astronomy’ or “Vedic astrology” and represents one of the six additional sciences to be studied along with the Vedas. Jyotiṣa concerns itself with the study and prediction of the movements of celestial bodies, in order to calculate the auspicious time for rituals and ceremonies.
General definition (in Hinduism)
Ayādi-ṣaḍvarga literally means “the group of six formulad starting with Āya” and refers to a set of forumulas provided in a text named Mānasāra (authoritative text dealing with temple architecture and town-planning).
The names mentioned below represent well-known groups of objects that always follow a certain serial order.
- Ṛkṣa Yoni
For instance, Vāra represents the group of seven days of the week while Rkṣa represents the group of twenty-seven nakṣatras (star-groups). Each one of these formulas is further documented within the text.
The remainder left after the application of the concerned formula determines the suitability of a dimension. For example, if the height of a proposed new building is to be determined from among the several alternatives suggested by the work, the vāra formula is applied for the height. If the remainder from this formula results in 4, it would indicate to the fourth day of the week, Wednesday. Since Wednesday is considered to be an auspicious day, it would be concluded that the measurement chosen is right.(Source): Hindupedia: The Hindu Encyclopedia
