Bhagavad Gita 15.3 — The axe of detachment
न रूपमस्येह तथोपलभ्यते नान्तो न चादिर्न च सम्प्रतिष्ठा। अश्वत्थमेनं सुविरूढमूलं असङ्गशस्त्रेण दृढेन छित्त्वा ॥
na rūpamasyeha tathopalabhyate nānto na cādirna ca sampratiṣṭhā | aśvatthamenaṃ suvirūḍhamūlaṃ asaṅgaśastreṇa dṛḍhena chittvā ||
Meaning
Its true form cannot be seen here — not its end, its beginning or its base. This deep-rooted tree must be cut down with the strong axe of detachment.
