svavākcyutāya niṃdyāya na vācyā yogajā kathā | nityabhaktāya dāṃtāya śamādi guṇine tathā
O ensinamento nascido do yoga não deve ser dito a quem caiu da própria palavra (da veracidade), nem a quem é censurável. Deve, porém, ser proferido ao sempre devoto, ao autocontrolado e ao que possui virtudes que começam pela serenidade.
Skanda (deduced from context)
Scene: A guru in a tīrtha-āśrama instructs a calm, self-controlled devotee while turning away a quarrelsome, blameworthy listener; palm-leaf manuscript of yoga-kathā remains closed for the unfit.
