Chapter 4, Verse 35
Part of 4: Jñāna Karm Sanyās Yog — ज्ञानकर्मसंन्यासयोगयज्ज्ञात्वा न पुनर्मोहमेवं यास्यसि पाण्डव। येन भूतान्यशेषेण द्रक्ष्यस्यात्मन्यथो मयि॥
yaj jñātvā na punar moham evaṁ yāsyasi pāṇḍava yena bhūtānyaśheṣheṇa drakṣhyasyātmanyatho mayi
Knowing that thou shalt not, O Arjuna, again be deluded like this; and by that thou shalt see all beings in thyself and also in me.
That, the knowledge of the Self mentioned in the previous verse, that is to be learnt from the Brahmanishtha Guru through prostration, estioning and service. When you acire this knowledge you will not be again subject to confusion or error. You will behold that underlying basic unity. You will behold or directly cognise through internal experience or intuition that all beings from the Creator down to a blade of grass exist in your own Self and also in Me. (Cf. IX.15XVIII.20)
