The four houses related to bhū loka (earth plane) are the Lagna (1st), Dhana (2nd), Sahaja (3rd) and Sukha (4th). Learn the meanings of these words well else you can never really understand the meaning of these houses. It is important to learn the principles involved in judging house results when the lord of a house is placed in any bhāva. The bhāveśa (lord of bhāva) is the real kartā (doer) for that bhāva (house). If it is well placed from (a) lagna as well as (b) that bhāva, it generally, augers good results as (a) an experience for the native and (b) as manifestation of the bhāva, respectively. In this manner learn the principles involved and how to study the bhāveśa.
