The attitude of the worshipper and the worshipped is the seed of devotion (bhakthi). First, the worshipper’s mind is attracted by the special qualities of the object of worship. The worshipper tries to acquire these special qualities. This is spiritual discipline (Sadhana). In the early stages of spiritual discipline, the distinction between worshipper and worshipped is clear, but as the sadhana progresses, it diminishes and, when attainment is reached, there is no distinction whatsoever. Whatever be the object of worship that you love and seek through sadhana, have firm faith that you and He are one. You must entertain only one wish: the realisation of the Lord (Iswara Sakshatkara). Give no room in the mind for any other wish. Then regardless of joy and sorrow, without any worry about your own satisfaction, you will engage in spiritual discipline firmly, uninterruptedly, with full conviction; and once you understand the Reality, you will have full contentment.
