Sāṅkhya Enumeration of Tattvas, Distinction of Puruṣa–Prakṛti, and the Mechanics of Birth and Death
तद्वत् षोडशसङ्ख्याने आत्मैव मन उच्यते । भूतेन्द्रियाणि पञ्चैव मन आत्मा त्रयोदश ॥ २३ ॥
tadvat ṣoḍaśa-saṅkhyāne ātmaiva mana ucyate bhūtendriyāṇi pañcaiva mana ātmā trayodaśa
അതുപോലെ പതിനാറിന്റെ കണക്കിൽ ആത്മാവിനെയാണ് മനസ്സ് എന്നു പറയുന്നത്. കൂടാതെ അഞ്ചു ഭൂതങ്ങൾ, അഞ്ചു ഇന്ദ്രിയങ്ങൾ, മനസ്സ്, ജീവാത്മാവ്, പരമപുരുഷൻ എന്നിവയെ എണ്ണിയാൽ പതിമൂന്ന് തത്ത്വങ്ങൾ ആകുന്നു।
According to the theory of thirteen elements, the sense objects — aroma, taste, form, touch and sound — are considered by-products of the interaction of the senses and physical matter.
This verse explains that different analytical traditions count the constituents of experience differently: in a sixteenfold count the mind may be identified with the self, while in a thirteenfold count the five elements and senses are grouped, and mind and self are treated as distinct—yielding thirteen.
In the Uddhava Gītā, Kṛṣṇa teaches Uddhava discriminative knowledge (tattva-viveka) so he can detach from bodily and mental identification and fix devotion on the true Self and the Supreme.
Treat thoughts and emotions as movements of mind, not your real identity; this reduces reactivity and supports steady sādhana—hearing, chanting, and remembering the Lord with clearer inner detachment.
