Surya Siddhanta
रहस्यम् एतद् देवानाम् न देयम् यस्य कस्यचित् । सुपरीक्षितशिष्याय देयम् वत्सरवासिने॥
This mystery of the gods is not to be imparted indiscriminately : it is to be made known to the well-tried pupil, who remains a year under instruction. [The commentary understands by this mystery, which is to be kept wjth so jealous care, the knowledge of the subject of this chapter, the deli- neation of an eclipse, and not the general subject of eclipses, as treated in the past three chapters. It seems a little curious to find a matter of so subordinate consequence heralded so pompously in the first verse of the chapter, and guarded so cautiously at its close.]
