त्रिग्रहोच्छेफलं प्रजातस्य नीचभावे च खेचरे !
राजयोगफलं नास्ति कलौ गर्गमतं स्मृतं !!
कलो नीचग्रहाभवे निष्फलं स्वोत्चखेचरे !
उच्चनीचौ राजयोगं नीचभवे दारिद्रकः !!
According to sage Garga, one born with three planets in exaltation signs,will not beget Rajayoga effects unless there is a planet in simultaneous debility.This applies to the Kali Yuga. In the said yuga,without a debilitated planet,an exalted planet will become ineffective.Only with simultaneous presence of exalted and debilitated planets,Raja yogas will fructify.With out debilitated planet,one with only an exalted planet will incur poverty.
I found this sloka in one of the texts on Nadi astrology. I believe this answers the doubts as to why a native with Pancha Maha purusha yogas will still lead a life of poverty.
