When one perceives Love of God inside, one will automatically love everyone.
Yog of Knowledge and Action
Chapter 4, Verse 35
yaj-jñātvā na punar-moham
evam yāsyasi pāṇḍava
yena bhūtāny-aśeṣeṇa
drakṣyasy-atman-yatho mayi
Possessing that knowledge, you shall not fall again into the mind‘s ignorance, O Pandava; for by this, you shall see all existences without exception in the Self, then in Me.
“Possessing that knowledge, you shall not fall again into the mind’s ignorance.” By surrendering humbly to the Master, and through the Grace of the Master, the Truth is revealed and one doesn’t fall back into ignorance. One perceives the vision of the Divine within oneself, and through that vision of the Divine within, all new karma that is created, is burned off straight away. When one sees unity everywhere, one overcomes grief and delusion.
Here Krishna addresses Arjuna as ‘Pandava’. Krishna says to him, “You shall see all existences without exception in the Self, then in Me.” First you perceive the Self, God, inside of you. Then, you perceive the depth of that Truth: “Everything is in My cosmic Body, there’s nothing outside of Me. It’s all in Me.” When one has the knowledge of the Self, when one has realised the Truth about God, one will not fall back into delusion. One perceives and recognises the Self as all-pervading and infinite, and treats all as one treats one’s Self. That’s what Christ says in the Bible: “Love the Lord your God with all your heart, with all your soul and with all your mind. And love your neighbour as yourself.” When one perceives this Love of God inside, one will automatically love everyone.
