स च तिथ्यात्मको मासश्चान्द्रः श्रवणभास्करः
And that lunar month, based on the tithi, is called Śravaṇa Bhāskara.
गौणोऽप्यसौ युगाद्यादेरनुरोधेन वर्धनात्
This is also considered secondary, increasing in accordance with the beginning of the yuga.
चैत्राद्याश्चान्द्रमासा ये द्वादशापि तु योगतः
The twelve lunar months, beginning with Caitra, are determined by their conjunctions.
विशाखयाद्येषु या वा तथा भाद्रपदेन वा
Whether among those beginning with Viśākhā or likewise with Bhādrapada.
योऽसौ यद्यपि चैत्रादौ नैष्ठिकोऽपि प्रलभ्यते 2.2.6.
Even if it is not found at the beginning of Caitra, it may still be obtained as Naiṣṭhika.
तथा च माससामान्ये योगेनायं भवेत्क्वचित्
Thus, in the general months, this may occur through conjunction at times.
संयुक्ता लभ्यते यत्र भवेद्राज्यविनाशनम्
Where the conjunction occurs, there will be the destruction of sovereignty.
दण्डद्वये भुक्तशेषे न भुञ्जीत कदाचन
When two daṇḍas remain after consumption, one should never partake again.
यत्र विंशत्तिथिस्तस्मात्सञ्चितैका भवेदिति
Where there are twenty tithis, from that, only one accumulated is to be considered.
स चाधिको यतो मासस्ततः स्यादधिमासकः
And since that month is excessive, it is called the intercalary month.
गशे राश्यंतरे सूर्यो यावद्गच्छति भानुमान्
As long as the Sun, the shining one, moves through the interval between signs.
वर्धते तिथयो यावत्तुलां याति दिवा करः
The tithis increase until the Sun reaches the sign of Libra during the day.
स्वभावात्समगत्या तु यतः संक्रमते रविः निशास्वपि तु सौरे ता एकस्मिंस्तिस्र इत्यपि
By its own nature and equal movement, when the Sun transits, even at night, those solar tithis may be three in one.
संपूर्णत्रिंशत्तिथिभिर्मास्येकस्मिन्यदा भवेत्
When there are thirty complete tithis in a single month.
भुक्तोच्छिष्टा तु तन्मासादसंस्पृष्टदिवाकरः 2.2.6.
The remnants consumed from that month are untouched by the Sun.
सार्धवर्षद्वये पूर्णे पतत्येवं निशाकरः तिथयस्ते नियोक्तव्या नरो न स्यात्स पूरणः
When two and a half years are completed, thus the Moon falls; those tithis must be assigned, and a person should not be the fulfiller.
नैर्ऋत्यांतं हितार्थाय जलकेतुर्निगच्छति
For the sake of benefit, the water-banner moves toward the southwest end.
अतः प्रेतक्रियाः सर्वाः कार्या मलिम्लुचेऽपि च
Therefore, all rites for the departed should be performed, even for the impure.
तदिदानीं प्रवक्ष्यामि कथितं च प्रसंगतः मलमासेऽपि तत्कार्यं विशि नष्टि सपिंडनम्
Now I shall explain, as it has been mentioned in context: even in an impure month, that rite should be performed, especially the sapiṇḍīkaraṇa ceremony.
यदा तु द्वादशो मासो दैवान्मलिम्लुचो भवेत्। तत्रैव यत्नात्कर्तव्या क्रिया प्रेतस्य वार्षिकी
But when the twelfth month, due to fate, becomes impure, then the annual rite for the deceased must be performed with effort in that very month.
मासांतरे तु पतिते तस्मिन्नेव मलिम्लुचे
If an impure month falls in between the months,
वर्ज्यं मासिकया श्राद्धमेकं तस्मिंस्त्रयोदशे
then the monthly śrāddha should be omitted once in that thirteenth (impure) month.
कुर्यात्पत्याब्दिकं कर्म प्रयत्नेन मलिम्लुचे
One should diligently perform the annual rite for the husband during the impure month.
तीर्थस्नानमलभ्यं तत्तदाद्यं देवदर्शनम्
Bathing at sacred places, the first viewing of deities, and similar acts are not to be undertaken.
आर्तवर्जं पुंसवनं पुत्रादिमुखदर्शनम् 2.2.6.
The rites of puṃsavana (for begetting a son), the first sight of a child, and others, except those done out of distress, are to be avoided.
मलमासेपि कुर्वीत नृपाणामभिषेचनम्
Even in an impure month, the consecration of kings should be performed.
मंत्रोपासां रहस्यं च महादानं सुमङ्गलम्
The worship of mantras, secret rites, great gifts, and auspicious ceremonies (may be performed).
उपग्रहं गवादीनामाश्रमांतरसंक्रमम्
The marking of cattle and similar acts, and the transition between stages of life (āśramas),
वर्षवृद्धिवृषोत्सर्गकन्या द्विर्नयनादि च
The annual increase, the release of bulls, the giving of a maiden twice, and similar acts,
एवमस्तं गते शुक्रे वृद्धबाल्ये च संत्यजेत्
Thus, when Venus sets, and in old age or childhood, these should be abandoned.
