Even in the three Upanishads discussed we do not explicitly find a doctrine outlining yoga. There is no systematic reflection on the yoga notions attempting to create coherence and clarification among them. There are no discussions justifying and making credible the extraordinary claims of yoga technologies. Further, by reading the texts alone one would not know how to practise yoga. The notions are just listed and are open to almost any interpretation. The texts are clearly not there to provide technical information about yoga.
The lack of systematic reflection has led some scholars to argue that at the time of the Upanishads there was no yoga doctrine (Larson 1989). However, one could counter-argue that in order for the yoga sign to make sense, there must have been an implicit doctrine giving them meaning and significance. Following this line of thought one would then look for concepts that formed a system with yoga; concepts required to make sense of yoga. So one could argue that the teachers did not find it necessary to present the yoga doctrine itself. They just wanted to signal that they used yoga for certain purposes – the main purpose of the text was symbolic communication. So we cannot exclude the possibility that there was an implicit yoga doctrine at the time yoga appeared, just because it was not presented.189
