How can I concentrate on God and attain the purity of a true devotee?

[Ms. Amudha asked: How can I reach the purity level of a true devotee. I am not expecting any miracle. But how can I concentrate on real goal, which is God and the practical path to attaining God’s grace? At Your divine feet (Um Patham paninthen iraiva) - Amudha]

Swami replied: As I have already stated, you must put forth efforts to attain more and more theoretical devotion. It means that you have to study spiritual knowledge, which will give rise to theoretical devotion. Once that theoretical devotion is intense enough, it will spontaneously lead to practice and the practice will yield its divine fruit. But before you attain that ripened divine fruit through practical devotion, you must protect the plant of your spiritual effort from the attack of the insects of aspiration for receiving some fruit in return from God. The insecticide to control the insects of aspiration is the true spiritual knowledge itself. That spiritual knowledge is attained from the divine preacher (Satguru).
