Who is speaking and story frame
ऋषिरुवाच
सत्यमुक्तं किन्त्विह वा एके न मनसोऽद्धा विश्रम्भमनवस्थानस्य शठकिरात इव सङ्गच्छन्ते ॥ २ ॥
ṛṣir uvāca
satyam uktaṁ kintv iha vā eke na manaso ’ddhā viśrambham anavasthānasya śaṭha-kirāta iva saṅgacchante.
Śrīla Śukadeva Gosvāmī replied: My dear King, you have spoken correctly. However, after capturing animals, a cunning hunter does not put faith in them, for they might run away. Similarly, those who are advanced in spiritual life do not put faith in the mind. Indeed, they always remain vigilant and watch the mind’s action.
