Jīva–Ātman Inquiry; Kṣetrajña Doctrine; Karma-based Varṇa; Four Āśramas and Sannyāsa Discipline
तं पूर्वापररात्रेषु युंजानः सततं बुधः । लब्धाहारो विशुद्धात्मा पश्यत्यात्मानमात्मनि ॥ ४७ ॥
taṃ pūrvāpararātreṣu yuṃjānaḥ satataṃ budhaḥ | labdhāhāro viśuddhātmā paśyatyātmānamātmani || 47 ||
Bậc trí, luôn chuyên chú vào pháp ấy trong phần đầu và phần cuối của đêm; chỉ thọ thực vừa đủ theo những gì có được, không tham cầu; tâm thanh tịnh, liền thấy Atman trong chính Atman.
Sanatkumara
Vrata: none
Primary Rasa: shanta
Secondary Rasa: bhakti
It teaches that liberation-oriented realization arises from steady meditation, purity of mind, and disciplined living—culminating in direct perception of the Self within oneself.
While framed in yogic language, it supports Bhakti by emphasizing inner purification and sustained remembrance; such steadiness makes the heart fit for unwavering devotion and God-centered contemplation.
Not a Vedanga lesson directly; the practical takeaway is sādhana-vidhi—timing discipline (night vigils) and regulated diet (labdhāhāra) as supportive observances for meditation.
