(CENtrifugal pressure supported Boundary Layer), may explain the power-law tail of the spectrum from black hole candidates in hard states, while a weak or no shock solution produces a dearth of hot electrons which may cause the weaker power-law tail in the soft states [@ct95; @mc10]. Moreover, a large number of authors have shown the formation of bipolar outflows from the post-shock accretion flow, both numerically [@mlc94; @msc96] as well as analytically [@lb05; @cd07; @fk07; @dc08; @dbl09; @kc13; @kscc13; @kcm14]. It is also interesting to note that, by considering a simplified inviscid accretion, and which has the right parameters to form a standing shock, @dcnc01 qualitatively showed that there would be no jets in no-shock or weak shock condition of the disc, or in other words, when the disc is in the soft spectral state. This indicates the conclusions of @gfp03. Such a scheme of accretion-ejection solution is interesting because, the jet base is not the entire accretion disc but the inner part of the disc, as has been suggested by observations [@jetal99; @detal12].

Although, most of the efforts have been undertaken theoretically to study steady shocks, perhaps transient shock formations may explain the transient events of the black hole
