Are Samatha and Vipassana mentioned in the Pali Canon as different styles/techniques of meditation? I've seen in a lot of discussions that there are two kinds of meditation methods with different but complementary goals: meditation for establishing tranquility (samatha) and meditation for establishing insight or clear vision (vipassana). 

But in a few places, some authors and practitioners say that both are not different styles, but two quatities and aspects that are developed during Samma Samadhi (Right Inmersion), and that in the Pali Canon there are no mentions of those two aspects being reached through different methods.

So, what do the Pali Canon tell us about this? Are these two different methods, or just two different aspects that are eventually developed hand-in-hand?

Thanks in advance for your time, wisdom and patience.

Kind regards!
Yes, but not as seperat for the taught purpose:


  "These two qualities have a share in clear knowing. Which two? Tranquillity (samatha) &amp; insight (vipassana)... A Share in Clear Knowing
