What is the significance of focusing on the Guru with 'undivided attention' and what is the promised outcome?

The principle of 'undivided attention' is described as the very secret of the Bhagavad Gita. Chapter 19 states that for 'those who think of Me with undivided attention,' Govinda provides for their well-being and security, a concept known as Yogakshema. A devotee who surrenders with an undivided heart can witness the wonder of devotion and experience the marvels of the Guru's skill. This constant unity is the key to receiving the Guru's full support and reaching the 'mine of happiness' in this world and the next.
