2. Differentiation of Paksha Bala

Both in Shuklapaksha and Krishnapaksha, the Tithi(s) are having qualitative distinctions. It has been fixed as 30 Tithis (Tidhis) covered in Shulklpaksha and Krishnapaksha. Out of which the merits and demerits of Tithis are assigned in the text Madhaveeya as under:

[Table 6.1 Pakshabala of Moon and Tithis.]

SN	Paksha	Tithi(s)	Results
1	Shuklapaksha	Shuklapaksha Pardipada	Struggling Efforts
2	Shuklapaksha	Dwiteeya, Trhutheeya& Chaturthi	Medium effects
3	Shuklapaksha	Panchami to Dashmai	Beneficial and providential
4	Shuklapaksha	Ekadashi to Pournami	Most Promising.
5	Krishna Paksha	Pradipada to Panchami	Positive and favourable.
6	Krishna Paksha	Shashti to Dashami	Medium Effects.
7	Krishna Paksha	Ekadashi to Amavasya	Most inauspicious.

Exceptionally, Krishna Paksha Trayodashi is also contemplated as qualitative if the Moon gets sufficient strength. The exceptions are prevailing all over as per the difference in locations and customs of every region.

The text of Phaladeepika confirms the same results in other words:—

During the main period of the Moon, the native gets all types of mental ecstasy, cherished desires, delicious food, desired wife and children, jewels, costumes, domestic animals, land properties and reverence from the scholars.

The Saint Mantreswara specifically determined the condition that the result of Moon shall be reckoned in line with its intensity. Moon gets Medium power till Shuklapaksha Panchami. From that Tithi to Krishna Paksha Panchami moon gets greater strength and from Krishna Paksha Shashti to Amavasya, it gets meager strength.
