  We interpret observed features of the black hole candidate GRS1915+105 in the
light of the advective flow paradigm. The light curve of this black hole is
seen to be of four classes, Soft, Hard, Semi-Soft and Intermediate. Each class
can display more than one type of light curve making altogether twelve or more
types of light curves. In each type, the mode of accretion may be one or more
of three types: which we identify as HW (hard state with winds), CC (Compton
cooling) and EA (enhanced accretion) respectively. Apart from these three
states there are two more fundamental states in a black hole accretion which
are soft and hard states. We also find that winds and outflows could soften
spectra in hard states and the enhanced accretion could harden the soft states.
These are observed in the spectra of GRS 1915+105. Generally, we find that
advective flow paradigm can satisfactorily explain all the features of the
enigmatic black hole GRS 1915+105.
