It is not artificial for a young child to practice walking; there is a natural propensity within the child to walk. But in a young child, the ability to walk has not yet developed. Therefore, the child practices. Similarly, it is our natural propensity to love God, but until the ability to love God has developed, it is also natural for us to practice loving God by performing sadhana-bhakti.
