से: Stimulus ~> Ancillary

Or are these Stimulus↝Source?? I feel like this is grammatically parallel to मैं तुमसे मिलता हूँ। "I meet you" which fits the Ancillary function, but on the other hand the source of the feeling is तुम.

• मैं
  I

  तुमसे
  you-INS

  प्यार
  love

  करता
  do

  हूँ
  am

  'I love you.' 001
