पुच्छे प्रगृह्य भुजङ्गीं सुप्तां उद्बोधयेच्च ताम् । निद्रां विहाय सा शक्तिरूर्ध्वं उत्तिष्ठते हठात् ॥ ३.१११ ॥

pucche pragṛhya bhujaṅgīṃ suptāṃ udbodhayecca tām । nidrāṃ vihāya sā śaktirūrdhvaṃ uttiṣṭhate haṭhāt ॥ 3.111 ॥

This sleeping she-serpent should be awakened by catching hold of her tail. By the force of Hatha, the Shakti leaves her sleep and moves upwards.
