Bhagavad Gita Chapter 14, Verse 27

ब्रह्मणो हि प्रतिष्ठाहममृतस्याव्ययस्य च | शाश्वतस्य च धर्मस्य सुखस्यैकान्तिकस्य च ||

brahmaṇo hi pratiṣṭhāham amṛtasyāvyayasya ca śāśvatasya ca dharmasya sukhasyaikāntikasya ca

For I am the foundation of Brahman, which is immortal, imperishable, eternal, and the absolute happiness of dharma.

Krishna concludes Chapter 14 with a profound revelation: 'Brahmaṇo hi pratiṣṭhāham'—I am (aham) the foundation (pratiṣṭhā) of Brahman (brahmaṇaḥ). 'Amṛtasyāvyayasya ca śāśvatasya ca dharmasya sukhasyaikāntikasya ca'—of the immortal (amṛtasya), imperishable (avyayasya), eternal (śāśvatasya), and the absolute happiness (sukhasyaikāntikasya) of dharma (dharmasya). This reveals Krishna's supreme position: He is the foundation of everything—Brahman, immortality, eternity, dharma, and ultimate happiness. Everything rests on Krishna. Understanding this helps you see that devotion to Krishna is not just a path—it's devotion to the very foundation of reality. When you serve Krishna, you're serving the source of everything. This is the ultimate truth that concludes the chapter on the gunas: Krishna is beyond all gunas, and He is the foundation of all that is eternal and true.
