Bhishma said 'I shall not, O son of Pritha, describe to you for four kinds of Yoga meditation. Obtaining a knowledge of the same, the great Rishis, attain to eternal success even in this world. Pleased with knowledge, with hearts engaged in Liberation, and conversant with Yoga, great Rishis, act in such a way that their Yoga meditation may get on properly.
भीष्म उवाच हन्त वक्ष्यामि ते पार्थ ध्यानयोगं चतुर्विधम्। यं ज्ञात्वा शाश्वती सिद्धिं गच्छन्तीह महर्षयः॥ यथा स्वनुष्ठितं ध्यानं तथा कुर्वन्ति योगिनः। महर्षयो ज्ञानतृप्ता निर्वाणगतमानसाः॥
