Each sadhana which is full impregnated with devotion or Divine
Concentration on Our Source is Great!

Without good intention not good result - yoga not different from full
ethic life!
Meditation is only self observing process which must be present in
all activities.

Meditation is not only outside state of consciousness or outside
state of pure self, because meditation is basically natural form in
outside life like concentration and samadhi.

Meditation is action without pose, or, when in action separate not
actor and observer, or, when can live in one continue consciousness
state without break with outside thinking about any form.
Meditation is very important because in higher yoga is part of
samyama. Samyama is Divine Concentration where meditation is between
state consciousness in which soul deep enter (samadhi) and state
consciousness in which have concentration - 216 samyamas (minimum)
have!

When meditation became full part of devotion soul can deeper enter in
process self-realization, and in next steps of god-realization.
