How does a devotee truly surrender to the Guru to receive their full grace?

To truly surrender, a devotee must approach the Guru with an undivided heart, as this is the key to witnessing the wonder of devotion. Chapter 19 explains this principle with the Lord's words, 'Ye yatha mam' (As they approach me...), which places the burden of initiative on one's own actions. The text clarifies that the benefit is proportional to the practice. A devotee must perform their spiritual exercises, trusting the Guru to provide support, much like being promised a bowl of milk for doing exercises. For those who think of the Guru with 'undivided attention,' their well-being and security (Yogakshema) are provided for. This demonstrates that true surrender is an active, focused practice, not a passive state.
