“The teacher decides which of the Tri Krama (three steps) is the best for the student:
Śikṣaṇa Krama requires a perfect knowing to transmit a strict practice,
without any compromise, as it should be in Vedic chanting for example.
Rakṣaṇa Krama is aimed at protection and preservation;
it promotes continuity in any levels like health, abilities, knowledge, etc.
Cikitsā Krama looks for adaptation, healing, recovering…”
– TKV Desikachar speaking with his senior Western students London 1998
