Surrender is not a one-time procedure. It is not that we surrender once, and we are done with it forever. We have to keep surrendering at every moment. In this process, there are innumerable obstacles. Our mind is made of Maya and it naturally runs towards the world. We need to beat this mind with the intellect. We also have saṁskārs of past lifetimes that must be countered. And then, we have the ignorance or agyān within us, which is the source of all the problems.
However, we must not feel disillusioned. Innumerable souls in the past have overcome these obstacles to perfect their surrender to God, and have attained Him; if we endeavor sincerely, we too will be successful.
First, we must illumine our intellect with the spiritual knowledge given to us by our Guru. Then, with this purified intellect we must work on the mind, to detach it from the world and attach it to Names, Forms, Pastimes, Virtues, Abodes and Saints of God. Along with our sincere efforts, we must pray to God and Guru for help, firmly believing that Their Grace can make us perfect our surrender.
To speed up the process of surrender, we should strengthen the sentiment, “God and Guru alone are mine.” When we develop love for God and Guru, surrender becomes natural and automatic. When we reach the state of complete surrender, the feeling “He alone is mine” will always remain in our mind, and all our thoughts and actions will be in consonance with it.
If we can keep increasing our desire to serve, that is also a very potent tool for progress.
