At the time of writing Yoga Makaranda (1934), the practice of tens, even hundreds of sun salutations had been in vogue as a health and fitness fad. Krishnamacharya seems to have felt this trivialised the surynamaskara. Krishnamacharya would still teach the stages of the sun salutalutation but as individual asana with long stays. He would occasionally teach the surynamaskara with mantras as we do in Vinyasa Krama.
In ashtanga vinyasa of course we only practice 5 A's and 5 B's. which is hardly excessive .
"One cannot have such a trivial attitude as expecting immediate benefits in auspicious matters like yogabhyasa, worship, sandhya vandanam (salutation to the sun) or chanting of mantras as though one were a laborer who does one hour of work and expects immediate payment. They should not lament that they have not received even one paisa for all the time spent on this. When this pattern of thinking begins, we enter a phase of deterioration day by day."

Question: What does the bhakti mean to a person who has no belief in Isvara?
Krishnamacharya: Love is bhakti for them
Here's a link to my presentation of how Krishnamacharya and Ramaswami would teach the sun salutation with mantra
and here's a link to the Surnamaskara for health in vogue at the time of Krishnamacharya writing Yoga makaranda.
And Thank you to Gabor for sending me this link to the Sandhya Vandam (salutation to the sun ritual)
