Siddhanta Shiromani (Crown of Treatises)

The Guru’s Grace and the Purpose of the Work

Having placed the lotus feet of the Master Guru in his heart with deep devotion, he who possesses an intellect that causes wisdom to shine—even from a mere fragment of realized knowledge—speaks. The expert Bhāskara Bhāskara II (1114–1185 CE), also known as Bhāskāracārya, the preeminent mathematician and astronomer of medieval India., out of affection for astronomers Gaṇakas, composes this clear Instruction for the Uninitiated Bālā-avabodha original: "vālā-avabodha"; literally "awakening for children," but here referring to a clear introductory explanation for students. titled the Crest-Jewel of Astronomical Treatises Siddhānta Shiromaṇi, which is adorned with elegant and pure prose.

The rest of the passage is clear in its meaning.

The Prayer and the Definition of Siddhānta

Now, the purpose of this request:

"May the virtuous not show disregard [for this work] because of its specific novelties. On the other hand, let the wicked laugh at me as they wish."

Next, we move to the definition of a Siddhānta Siddhānta A comprehensive astronomical treatise that covers time from the creation of the universe to its dissolution.. A work is called a Siddhānta when it deals with the measurement of time—from the smallest unit of a moment Truṭi to the end of a Great Age Kalpa—through the various divisions of planetary movement and mathematical calculation. This is divided into two parts in the science of computation...
