Fix thy mind in Me only, thy intellect in Me, (then) thou shalt no doubt live in Me alone hereafter.

Set your mind on me alone, let your understanding enter into me. Then you will dwell in me alone hereafter; of this there is no doubt.

Krishna now gives Arjuna direct instruction. He should place his mind on Krishna alone and let his understanding (buddhi) enter into him. Then he will dwell in Krishna from that time on, without doubt. This verse opens a graded series of instructions, each one offering a more accessible path if the previous one proves too difficult. It begins at the highest level: complete absorption of mind and understanding in God. The sequence that follows shows great sensitivity to differing human capacities.
