GURBAKHSH, BHĀĪ, Gurū's masand or saṅgat leader at Delhi, served Gurū Har Krishan (1656-64) with devotion when the latter was in the city in March 1664 at the summons of Emperor Auraṅgzīb. The Gurū had a sudden attack of smallpox and lay critically ill. Bhāī Gurbakhsh, seeing the end near, gently begged him to nominate a successor. Gurū Har Krishan could barely utter the words: "Bābā Bakāle," referring to Gurū Tegh Bahādur, who lived at Bakālā, as the future Gurū. According to Bhāī Santokh Siṅgh, Srī Gur Pratāp Sūraj Granth, Bhāī Gurbakhsh later went to Bakālā, made his obeisance to Gurū Tegh Bahādur and gave him an account of Gurū Har Krishan's last days in Delhi.
