किं पुनर्ब्राह्मणाः पुण्या भक्ता राजर्षयस्तथा ।अनित्यमसुखं लोकम् इमं प्राप्य भजस्व माम् ॥
kiṃ punarbrāhmaṇāḥ puṇyā bhaktā rājarṣayastathāanityamasukhaṃ lokam imaṃ prāpya bhajasva mām
How much rather then holy Brahmins and devoted king-sages; thou who hast come to this transient and unhappy world, love and turn to Me.
Gītā 9·33The way to liberation is to turn from the outward to the inward, from the appearance created by the material life which lays its burden on the mind and imprisons it in the grooves of the life and the body to the divine Reality which waits to manifest itself through the freedom of the spirit. Love of the world, the mask, must change into the love of God, the Truth.
This world is as the Gita describes it, anityam asukham, so long as we live in the present world-consciousness; it is only by turning from that to the Divine and entering into the Divine Consciousness that one can possess, through the world also, the Eternal.

The Gita cannot be described as exclusively a gospel of love. What it sets forth is a Yoga of knowledge, devotion and works based on a spiritual consciousness and realisation of oneness with the Divine and of the oneness of all beings in the Divine. Bhakti, devotion and love of God carrying with it unity with all beings and love for all beings is given a high place but always in connection with knowledge and works.
