numerous birds and which has the melodious strains of
music of celestial damsels.
Rohini Yoga is the period of a day when the Moon passes
through the star Rohini in the dark half of the lunar month of
Ashadha.
In this connection, Mr. Chidambara Iyer, very aptly remarks :
"These prefatory remarks clearly shew that what follow are
important scientific truths in the eyes of Hindu astronomers : that the
weather indications of one single day in a year should form the subject
of so much calculation with the Hindus in determining the future
agricultural prospect of the land while to the inexperienced eye of a
western man of science, the day appears as indifferent or otherwise as any
other day of the year argues that modern science is still far behind in her
investigations of the laws of nature."
प्राजेशमाषाढतामिस्रपक्षे क्षपाकरेणोपगतं समीक्ष्य ।
वक्तव्यमिष्टं जगतोऽशुभं वा शास्त्रोपदेशाद्ग्रहचिन्तकेन ॥४॥
योगो यथानागत एव वाच्यः स धिष्ण्ययोगः करणे मयोक्तः ।
चन्द्रप्रमाणद्युतिवर्णमागैरुत्पातवातैश्च फलं निगद्यम् ॥५॥
Slokas 4-5.—An astronomer should carefully observe
the Moon's conjunction with Rohini in the dark half
of Ashadha and then predict its good or bad effects to
mankind according to the tenets of the Sastras. How
a future conjunction of the Moon with the asterism
should be foretold has been explained by me in my work
Panchasiddhantika under the head of "Conjunction
with Fixed Stars". The effects, however, must be
declared as deduced from the Moon's size, brightness,
colour, direction and from portents at the time and
the winds.
