Karika 37

सर्वं प्रत्युपभोगं यस्मात्पुरुषस्य साधयति बुद्धिः।
सैव च विशिनष्टि पुनः प्रधानपुरुषान्तरं सूक्ष्मम्॥ ३७॥

Translation by Henry Thomas Colebrooke (1837): Since it is intellect which accomplishes soul's fruition of all which is to be enjoyed, it is that, again, which discriminates the subtle difference between the chief principle (pradhána) and soul.

Translation by John Davies (1881): As it is 'intellect' which accomplishes all the fruition of the soul, so also it is that which discriminates the subtle difference between the chief principle (Pradhāna = Prakṛiti) and the soul.

Translation by Ganganath Jha (1896): Since it is Buddhi that accomplishes the Spirit's enjoyment, and again it is Buddhi that exposes the subtle difference between Nature and Spirit.

Translation by Nandalal Sinha (1915): (The other Indriyas present all objects to Buddhi, so that they may be exhibited to Puruṣa), since it is Buddhi which accomplishes the experience of Puruṣa in regard to all (objects at all times). And it is that, again, which discriminates the subtile difference between the Pradhâna and Puruṣa.

Translation by Har Dutt Sharma (1933): As it is the intellect which brings about the entire enjoyment (of objects), so it is again that (very intellect) which discriminates the subtle difference between the Nature and the Spirit.

Translation by Radhanath Phukan (1960): The materials worked upon by all other organs being presented to Buddhi, it is the Buddhi which brings about the enjoyment of the Puruṣa in all matters, and it is that Buddhi again which reveals to the Puruṣa the incomprehensible difference between the Prakṛti and the Puruṣa (See Kārikā LXIV).

Translation by Swami Virupakshananda (1995): Because, it is the Buddhi that accomplishes the experiences with regard to all objects to the Puruṣa. It is that again that discriminates the subtle difference between the Pradhāna and the Puruṣa.

Translation by G. Srinivasan (recent): A comprehensive and extraordinary use can be made in the following way. The potential of the Purusha can be attained from the minute coherent state hidden inside the Purusha by repeated precisely triggered inputs to initiate the primary interactions.
