Every human being needs to cultivate the spirit, irrespective of his beliefs. All need devotion. It is only spirituality that can purify the heart and mind of man. The second requirement is morality. Morality helps to purify Vaak (speech). The third is Dharmikam (Righteousness). All righteous deeds done by the body or hands sanctify a man. It is through spirituality, morality and righteousness that the three instruments get purified. Only the one who has achieved this triple purity can realise the Divine, if any of these instruments are impure, he cannot realise the Divine.
