Every house of Prashana Kundli is equally important as considered in Janam Kundli. Here, every house shows not about the question but also play important role in fulfilling of the object of the question. The sign of the Lagna is the 'querist' and the other Bhavas are the querent's wealth, brothers, etc. as we see in Janam Kundli
As per “Shatpanchasika” of Prithuyasas those Bhavas are associated with or aspected by their lords or benefics are said to thrive well. Similarly, those conjoined with or aspected by malefics will suffer annihilation. The Karkattwa (significance) of Bhavas are same as suggested for Janam Kundli.
Generally a Bhava gets strengthened if it is in “Subhakaratari yoga or if Kendras are occupied by benefics.
In Prashan Kundli those Bhavas are aspected by or conjoined with their lords or by Jupiter or Mercury or Venus gives good result. Similarly, those Bhavas have benefics in the 2nd, 7th and 12th or 4th and 10th from them; can also give good result and therefore considered as favourable.
Lords of the 6th, 8th and 12th are considered malefic or evil. The benefic nature of a Bhava is destroyed if the lord of 6th, 8th and 12th house makes any PAC (Placement, Aspect or Conjunction) connection with it.
Similarly, occupation of natural enemy planet of the lord of the Bhava makes it afflicted. Bhava also become afflicted if the Bhava or its lord or the Karaka is weak. The intensity of the affliction of a Bhava is ascertained by the intensity of the affliction it is receiving through evil associations or aspects.
However, these combinations should not be applied as it is. Since some planets have lordship of two houses, the affliction due to lordship of the 8th or the 12th or the 6th gets neutralised under certain conditions.
In view of above facts, it is very much clear that a Bhava can be afflicted by 21 ways. Out of these 21 ways of affliction, even if a Bhava is under the affliction by two or more ways, then the Bhava will be considered as a weak or ruptured Bhava.
In addition to above, if the lord of the 8th from a Bhava or Saturn transits on that particular Bhava and if at the same time, the Dasa or Antardasha of 6th, 8th or 12th lord is operating, then the Bhava concerned will come under sever affliction. Diseases signified by that house can be experienced by the native during that period.
Novamsa position of a planet adds additional quality of giving good or bad results of a Bhava. Prashan Marg says that strong benefic can give rise to exclusively good or exclusively evil results according to its strength.
If a favourable planet is in Vargottam then the effect will be full. If it is in own Navamsa or in a friendly Navamsa, the effects will be half and if in the Navamsa of his enemy, the results will be very little.
Similarly, an unfavourable planet will bring very little unfavourable result if it is in Vargottam, mixed unfavourable result if it is in his own or friendly Navamsa but if it is in the Navamsa of his enemy, then its evil effect will be intensive.
If the lord and the Karaka of a Bhava are strong and occupy favourable houses, then the full significances of the Bhava can be realised. On the other hand, if they are weak and occupy the 6th, 8th or 12th house then the results of the concerned Bhava will be negative.
In Prashan Marg suggest that in Prashan Kundli the disposition of the lord and the Karaka in favourable and unfavourable houses should be seen from Lagna only.
In case, if the lord and Karaka are strong but are situated in 6th, 8th and 12th, then though the effects of Bhava can be experienced but the native will not enjoy them. On the other hand, if the lord and Karaka are weak but are in good positions, then the little effect will be experienced by the native.
It should be remembered that strength of a planet also depend on it own, exaltation, vargottam and friendly places. Strength of the lord increases the strength of the Bhava and its position influence the native.
Amongst Bhava and its Karaka, if one is strong and the other is weak, then mixed influence will be experienced. Placement od benefics in the 3rd, 6th, 8th and l2th house is unfavourable while position of malefics in the 3rd, 6th and 11th is favourable.
After the Lagna, 5th and 9th houses are the other two houses that are equally important. Placement of benefics in these three Bhavas gives excellent result while malefics gives their worst unfavourable result.
Placement of benefics strength the houses while malefics destroy them. Malefic planets in the 6th confer all the articles governed by them but the Bhava gets spoiled. Especially In questions of diseases, an malefic planet in the 6th house is harmful.
Benefics in the 6th house destroy enemies while malefics increase them. 8th and 12th houses of the Prashan Kundli should be empty as all planets are harmful in these houses.
Placement of various planets in a house will indicate its favourable or unfavourable effect on that house as per their nature characteristics. A malefic planet in Lagna indicate failure, diseases in the head, sorrows, dishonor, displacement, loss of money, pains all over the body and discomfort in all ways.
A benefic will indicate general comfort, success, good health, financial prosperity, fame and promotions to higher positions.
A malefic planet in the 2nd house signify loss of ancestral property, diseases in the face, sickness for the family members, diseases in the right eye, scandals and loss of vessels while a benefic will show increase of family wealth, gains of vessels, family amity and happiness.
A malefic in the 3rd house will indicate misfortunes of brothers, misunderstanding with friends, diseases in neck and right ear and bad conduct. A benefic will indicate happiness of brothers, courage, help from others, good conduct and good health.
A malefic in the 4th house shows distress of mother and maternal relations, loss of cattle, beds, cots, landed property and vehicles, heart trouble, general misery and discomfort due to impure water, while a benefic in the 4th house will indicate vehicles, lands, cattle, beds and general prosperity and good health.
5th house is as important as Lagna and therefore malefic in this house indicates illness, death or danger like accident of children, loss of Sanchita Karma, mental uneasiness, lose the spirit of optimism and enthusiasm, irritable temperament and illness of guru. Effects will be more sever if it is afflicted.
Benefics indicate birth of children or their good health, peace of mind, starting of higher education, influence and increase of good deeds etc.
