Here in this ashram there is a lot of talk about nirvikalpa and savikalpa samadhis, also known as asamprajnata and samprajnata samadhis. SN nicely provides a way of turning this on its head by identifying nirvikalpaka and savikalpaka pratyaksha from Nyaya. SN translates these as "indeterminate'' and "determinate" perception or knowledge.
What is interesting is that the same terms are used, but in such a way that sa-vikalpa, i.e., recognizing the characteristics of the object, results in fuller knowledge of the thing, which is straightforward enough. The yogis and jnanis who seek nirvikalpa realization are in fact disowning the very specificity of the Absolute Truth, since they believe direct knowledge of the Supreme can only be had through negation. (Commentary to Section 1.3 of Bhagavat-sandarbha by SN).
At the very beginning of perception one obtains indeterminate knowledge in the form of mere observation. It is like the cognition of an infant or the dumb, arising purely out of the object without any distinction of quality and qualified. (Sloka-vartika of Kumarila Bhatta 4.112)
More shall have to wait. I am out the door and on my way to Gauda Desh. And so I leave you, friends, with this Ray Shekhar pada--

Madhura madhura is Gaura Kishora,
madhura madhura his dance,
Madhura madhura are all his companions,
madhura their joyful fair.
Madhura madhura plays the mridanga,
sweet are the sounds that they pull
The devotees are drunk with sweet madhura rasa,
madhura are their melodies.
Madhura madhura are the waves of Gaura's movement,
Madhura madhura his gait,
Madhura madhura is his beautiful visage,
sweet his effulgence bright.
Madhura madhura are his lips, brighter
than the moon his madhura smile,
Madhura is his anxious mood, madhura his love,
and ever sweet his madhura speech.
Madhura madhura are his aruna eyes,
giving sweet hints as he looks,
Oh that cloud of sweet prema has rained,
but I have been left high and dry.
