Tämä on pätkä kRSNa-yajur-vedaan kuuluvasta yoga-tattva-upanishadista, joka
lienee melko nuori (n. 1500-luvulta??):
50-53. By thus retaining the breath as long as he likes, Kevala Kumbhaka
(cessation of breath without inspiration and expiration) is attained. When
Kevala Kumbhaka is attained by one and thus expiration and inspiration are
dispensed with, there is nothing unattainable in the three worlds to him. In the
commencement (of his practice), sweat is given out; he should wipe it off. Even
after that, owing to the retaining of the breath, the person practising it gets
phlegm. Then by an increased practice of Dharana, sweat arises.
54. As a frog moves by leaps, so the Yogin sitting in the Padma posture moves on
the earth. With a (further) increased practice, he is able to rise from the
ground.

55. He, while seated in Padma posture, levitates. There arises to him the power
to perform extraordinary feats.
56. He does (or should) not disclose to others his feats of great powers (in the
path). Any pain small or great, does not affect the Yogin.
57. Then excretions and sleep are diminished; tears, rheum in the eye, salivary
flow, sweat and bad smell in the mouth do not arise in him.
58-60. With a still further practice, he acquires great strength by which he
attains Bhuchara Siddhi, which enables him to bring under his control all the
creatures that tread this earth; tigers, Sarabhas (an animal with eight legs),
elephants, with bulls or lions die on being struck by the palm of the Yogin. He
becomes as beautiful as the god of love himself.
61-62. All females being taken up with the beauty of his person will desire to
have intercourse with him. If he so keeps connection, his virility will be lost;
so abandoning all copulation with women, he should continue his practice with
great assiduity. By the preservation of the semen, a good odour pervades the
body of the Yogin.
