I agree that Jagya is the one who did all that and Gauri was not at fault. But after marriage, the way Gauri bashed Anandi just because she was there makes Gauri at fault too.
Gauri went to Haveli before she married to Jagya & knew that he was already married..
Before taking an important step like marriage ,...any girl consults parents,elders,classmates or friends...
(1) Gauri's parents warned her fearing of Jagya's first marriage...Gauri never cared their advice...
(2) Also she never heeded good advice of elders like bade papa...
(3) Gauri never cared for the good words of friends like shivani
(4) Gauri never had any women classmates to suggest her...
She had a common classmate of Jagya who is working as Jaitsar doctor(forgot his name)..Gauri never heeded to his good words..
When some one has problems with every one in the world...
Then the fault is certainly not with the world...but with the person itself...
Being a major doesn't mean that u Hv a right to sleep with the one u fancy...but it means that u Hv reached an age to think independently & can take care of yourself physically...psychologically...legally...& consciously...
Why can't she slap Jagya & throw him out when she found that she was deceived by him regarding his marriage?who cd stop her, & what cd prevent her?...none & nothing...
Gauri is a willfull home breaker ...
she loves whatever she likes...irrespective of whether it is beneficial to her or not...
This is called as preyo marg, as per katopanishad...which leads to self destruction & bondage...
The other path ,is known as 'shreyo marg'.the tough path of truth,that allows personality development & liberation ...being followed by Anandi...
