Ramanuja interprets  this more closely and explains that – “jñāna is knowledge of (Me) the Universal Truth whereas vijñāna is the study of Myself in multitudinous distinctive forms that this Truth disperses into – both animate and inanimate”. In other words jñāna is meditative and draws towards the underlying Oneness of all things while, vijñāna is external – it measures, dissects, analyses. As the aspirant or sādhak painstakingly collects the knowledge of smaller truths step by step, he reverses this dispersal in his own consciousness, tending towards pragyānam Brahman  or the Ultimate Truth paradoxically the Unknown.

So the entire educational process should chip away at this ephemeral ti and lead the student to samyam ( saMyama ) or equipoise.
