Bhagavad Gita Chapter 12, Verse 4

संनियम्येन्द्रियग्रामं सर्वत्र समबुद्धयः | ते प्राप्नुवन्ति मामेव सर्वभूतहिते रताः ||

sanniyamyendriyagrāmaṁ sarvatra samabuddhayaḥ te prāpnuvanti mām eva sarvabhūtahite ratāḥ

Those who control all the senses, maintain equal mind everywhere, and are engaged in the welfare of all beings—they also attain Me.

Krishna completes his description of the impersonal path, explaining its difficulty. 'Sanniyamyendriyagrāmaṁ'—controlling all the senses (sanniyamya indriya-grāmam). 'Sarvatra samabuddhayaḥ'—with equal mind everywhere (sarvatra samabuddhayaḥ). 'Te prāpnuvanti mām eva'—they (te) also attain Me (mām prāpnuvanti eva). 'Sarvabhūtahite ratāḥ'—engaged in the welfare of all beings (sarvabhūtahite ratāḥ). This verse completes the thought from verse 12.3: those who follow the impersonal path can also reach Krishna, but it requires immense discipline—controlling all senses, maintaining equanimity everywhere, and dedicating oneself to the welfare of all. This sets up verse 12.5, which will emphasize the ease of the devotional path. The impersonal path works, but it's difficult.
