When Lord Kṛṣṇa delineates the yoga system to Arjuna, Arjuna says that the practice of this system is not possible for him.
- arjuna uvāca
- yo 'yaṁ yogas tvayā proktaḥ
- sāmyena madhusūdana
- etasyāhaṁ na paśyāmi
- cañcalatvāt sthitiṁ sthirām
"Arjuna said: O Madhusūdana, the system of yoga which You have summarized appears impractical and unendurable to me, for the mind is restless and unsteady." (BG 6.33)
But the Lord says:
- yoginām api sarveṣāṁ
- mad-gatenāntarātmanā
- śraddhāvān bhajate yo māṁ
- sa me yuktatamo mataḥ
"Of all yogīs, the one with great faith who always abides in Me, thinks of Me within himself, and renders transcendental loving service to Me is the most intimately united with Me in yoga and is the highest of all. That is My opinion." (BG 6.47) So one who thinks of the Supreme Lord always is the greatest yogī, the supermost jñānī, and the greatest devotee at the same time. The Lord further tells Arjuna that as a kṣatriya he cannot give up his fighting, but if Arjuna fights remembering Kṛṣṇa, then he will be able to remember Kṛṣṇa at the time of death. But one must be completely surrendered in the transcendental loving service of the Lord.
