The knowledge ‘I am’ is ever there, residing in all at all times. There exists not a single thing devoid of the ‘I am’, it expresses itself through the five elements and three qualities. As is the combination of the elements and qualities so is the expression of ‘I am’. This expression could be good or bad depending on the combination, but the ‘I am’ itself stands in its purity. Understanding the ‘I am’ is the very basis of the teaching, that done, there remains nothing further to be understood. What follows hereafter is the ‘Sadhana’ (practice), which is the meditation on the ‘I am’. Your earnestness, sincerity and intensity of the practice would determine further progress.
