Gita's Samkhya is NOT DIFFERENT 

"Only the ignorant speak of devotional service [karma-yoga] as being different from the analytical study of the material world [Sankhya]. Those who are actually learned say that he who applies himself well to one of these paths achieves the results of both." (Gita 5.4)

You are not a Hindu and so you would not know this. Do you have any proof at all that This Sankhya is different? Why would Sri Krishna say this if it were different. He would have said so!

Sri Krishna in the Gita (10.26)
"Of all trees I am the banyan tree, and of the sages among the demigods I am Narada. Of the Gandharvas I am Citraratha, and among perfected beings I am the sage Kapila."

I am also going to post these quotes into the main article to clear up any confusion.
