Sihasana style the most right methode?

[kullatiro]

Traditionally the position
generally recommended
for dying is to lie down on
the right side, taking the
position of "the sleeping
lion," which is the posture
in which Buddha died. The
left hand rests on the left thigh; the
right hand is placed under the chin,
closing the right nostril. The legs are
stretched out and very slightly bent.
On the right side of the body are
certain subtle channels that
encourage the "karmic wind" of
delusion. [1] Lying on them in the
sleeping lion's posture, and closing
the right nostril, blocks these channels
and facilitates a person's recognition
of the luminosity when it dawns at
death. It also helps the consciousness
to leave the body through the
aperture at the crown of the head, as
all the other openings through which
it could leave are blocked
