This also explain and justify Guruma's rude treatmant toward Saloni too, who doesn't want to give Nahar a hope of new life because Nahar's acceptance of death only can give her son Amrit a new life, also the way baba and disciple treat Saloni going against guruma, the holy water she got first time gave Nahar new hope and desire to live and second time having same water which should cure him fully made him do such a act that Nahar with conscious mind never commit. All was part of game plan and magic of the mystic water.
Now Amrit's behaviour toward Saloni one moment he sympathize with her and pain she is going through, thinks about her and wants to help her and next minute he denies it, also lead her to river where he drown, goes into the water as Nahar but comes out as Amrit and him not knowing what happen to Nahar, sending same Ganesh idol and promise to help her but when she comes and ask for help the way he acted which Amrit wouldn't do then the dilemma he went thru, guruma lying about her being his birth mother and he come back exact looking like Nahar and act as well but with Guruma's exit soon and with Saloni and family by his side he will get his existence and we will have our Nahar. generally this type of souls have evil intention and if that is case then Saoni have to fight one more battel and deal with Devil to get her SUHAAG.where he have control over everthig home , property and over Nahar's Body.
This is first time i started a new topic and also not sure about my thought, could be totally wrong here but couldn't stop myself to express.
