“In addition, the use of Kriyā,
without a knowledge of the individuals Doṣa
is certainly going to do more harm than good.

Doṣa, briefly, means the constitution of the individual;
some are fat, some tend to get a lot of colds,
some have acid problems, some are nervous.

So different beings show different predominances in the Doṣa,
and Kriyā must be considered in relation to these varying constitutions.”

– TKV Desikachar from lectures on ‘The Yoga of T Krishnamacharya’,
given at Zinal, Switzerland 1981.
