sarvasrotonibandhena prāṇaśaktyordhvayā śanaiḥ |
pipīlasparśavelāyām prathate paramaṁ sukham || 67 ||
Translation
By blocking all the channels (of perception) the prana-shakti moves slowly upwards (through the spinal column). At that time, feeling the sensation of an ant crawling in the body, one experiences the supreme bliss.
