Six respirations constitute the period of time one Pala. Sixty such Palas constitute one Ghaṭī. Sixty Ghaṭīs constitute one day and one night. (6 x 60 x 60 = 21600).

Yoga (school of philosophy)
Source: ORA: Amanaska (king of all yogas): A Critical Edition and Annotated Translation by Jason BirchAhorātra (अहोरात्र) refers to the “time of one day and night”, according to the Amanaska Yoga treatise dealing with meditation, absorption, yogic powers and liberation.—Accordingly, as Īśvara says to Vāmadeva: “[...] [Now], I shall define the nature of that highest, mind-free absorption which arises for those devoted to constant practice. [...] By means of an absorption for a day and night (ahorātra), the Yogin who is steady in his seated posture knows smells from afar, because of the cessation of the activity of his mind. [...]”.

Yoga is originally considered a branch of Hindu philosophy (astika), but both ancient and modern Yoga combine the physical, mental and spiritual. Yoga teaches various physical techniques also known as āsanas (postures), used for various purposes (eg., meditation, contemplation, relaxation).
In Buddhism
Mahayana (major branch of Buddhism)
Source: De Gruyter: A Buddhist Ritual Manual on AgricultureAhorātra (अहोरात्र) refers to “day and night” (recitation of a mantra), according to the Vajratuṇḍasamayakalparāja, an ancient Buddhist ritual manual on agriculture from the 5th-century (or earlier), containing various instructions for the Sangha to provide agriculture-related services to laypeople including rain-making, weather control and crop protection.—Accordingly, [as the Bhagavān teaches an offering manual]: “A wax Garuḍa should be made. [...] Having placed it at a high place [covered] with cloths of various kinds [and colours], the mantra should be recited day and night (ahorātra) a thousand times. If there is no body-energy, one should take white foods. Besides one should bathe and it should be thus [continued to be] practised. [...]”.

Mahayana (महायान, mahāyāna) is a major branch of Buddhism focusing on the path of a Bodhisattva (spiritual aspirants/ enlightened beings). Extant literature is vast and primarely composed in the Sanskrit language. There are many sūtras of which some of the earliest are the various Prajñāpāramitā sūtras.
India history and geography
Source: Google Books: Studies in the History of the Exact Sciences (history)Ahorātra (अहोरात्र) refers to a “nychthemeron” (a period of 24 hours).—From about the fourth century A.D. up to recent times the water clock of the sinking bowl type (Ghaṭikā or Ghaṭīyantra) has been the chief device in India for measuring time. The instrument consists of a hemispherical bowl (ghaṭikā or ghaṭī) with a minute perforation at the bottom. When this bowl is placed on the surface of water in a larger vessel or basin (kuṇḍa, kuṇḍikā, kuṇḍī), water slowly percolates into the bowl through the perforation. When the bowl is full, it sinks to the bottom of the vessel with a clearly audible thud. The weight of the vessel and the size of the perforation are so regulated that the bowl sinks sixty times in a nychthemeron (ahorātra). Thus the time taken for filling the bowl once is one-sixtieth part of a nychthemeron, or twenty-four minutes. This was the standard unit of time measurement in India and is called ghaṭikā or ghaṭī after the name of the bowl. The ghaṭikā is subdivided into sixty vighaṭikās, which are also called palas.

The history of India traces the identification of countries, villages, towns and other regions of India, as well as mythology, zoology, royal dynasties, rulers, tribes, local festivities and traditions and regional languages. Ancient India enjoyed religious freedom and encourages the path of Dharma, a concept common to Buddhism, Hinduism, and Jainism.
