The unity of samadhi and prajna Does any extant tradition claim that the unity of samadhi and prajna^ is actual from the beginning of the bodhisatva path, so that it is available to the neophyte - just with less power of something similar to more advanced bodhisatvas?
^e. g. Chinul:

Samadhi being prajna, it is quiescent and yet always knowing.

or Platform Sutra:

To argue whether prajna or samadhi comes first would put one in the same position as those who are under delusion... a lamp and its light.

So you can see, they are one, yet - perhaps - not everyone realizes this in their practice?
Just asking because I think it may be the meaning of human life etc..
Of course it is.  You can't have prajna without samadhi.  Think of a shovel versus a backhoe.  With a little shovel you can clear away a little debris and dig little holes.
With a backhoe, you can move mountains.  So to with concentration and wisdom.  Your samatha practice is the tool that allows you to clear away your own obstacles and access insight and wisdom.  And just like in the shovel example with the little samadhi of the novice comes little prajna; with the big samadhi of the adept comes bigger prajna.
