समान उ एवाय चासौ चोष्णोऽयमुष्णोऽसौ स्वर इतीममाचक्षते स्वर इतिप्रत्यास्वर इत्यमुं तस्माद्वा एतमिमममुंचोद्गीथमुपासीत ॥ २ ॥
In plain words
This breath and that sun are identical; both are warm. They call this breath 'svara' and that sun 'pratyasvara'. Therefore, let a seeker meditate upon this breath and that sun alike as the Udgītha.
Close to the Sanskrit
Equal indeed is this one and that one; warm is this, warm is that. Svara they call this, pratyasvara that. Therefore one should meditate upon this very prana and that sun as the Udgitha.
