	The yoga scholar Elliott Goldberg comments that the photographs of Krishnamacharya's schoolboy pupils in the poses "don't truly capture yogins using their body as a tool for spiritual development either. In fact, the photos demystify whatever spirituality may obtain to the exercises." He adds that the group photographs are "showy ... eye-catching tricks", with boys in familiar asanas but arranged in a pyramid. The vinyasa system of yoga, too, was in Goldberg's view "spectacularly different" from anything practised in India at the time; he is dismissive of Krishnamacharya's "spurious claim for the ancient origin of Vinyasa yoga", citing Singleton's analysis in "Yoga Body" of its origins in Surya Namaskar, suggesting "self-aggrandizement and self-protection" as the motives. Despite all this, Goldberg states that Krishnamacharya's main interest in yoga was to nourish spirituality ("adhyatmika krama"), quoting his words in "Yoga Makaranda": "Once you stop the oscillating nature of mind, you can reach the level[s] of dhyana, nididhyasanam, and samadhi [the highest levels of Patanjali's eight-limbed yoga]" and through that you can see the atma[n]. He notes that Krishnamacharya was following the traditional interpretation of Patanjali's "Yoga Sutras", that the eight limbs formed a sequence of steps.
