Brihat Parashara Hora Shastra
षष्ठेऽष्टमे तृतीये वा स्वस्वनीचगता ग्रहाः । लग्नं पश्येत् स्वभोच्चस्थो लग्नपो राज्ययोगदः ॥ १९॥
If Ari, Randhr and Sahaj Bhava are occupied by debilitated Grahas, as Lagn‟s Lord is exalted, or is in own Bhava and gives a Drishti to Lagn, there is a Raj Yog.
english translation
SaSThe'STame tRtIye vA svasvanIcagatA grahAH । lagnaM pazyet svabhoccastho lagnapo rAjyayogadaH ॥ 19॥
