In the primary level of devotion we think that the earth exists only for human beings.
The second level of devotion reveals that the earth exists not only to cater to our own welfare, but also to promote the wellbeing of all organisms that coexists with us. When we reach this level, our patience and tolerance increase and grow. We also begin to understand that every single thing we do has a direct or indirect impact on other beings.
At the third level of devotion we become aware of our contribution to this world through our thoughts, words and deeds. A new awareness makes us recognise that although contributing socially to the world is good, we must also contribute a spiritual legacy for the future.
Next in the progressive level of devotion we realise that a clean and pure mind is as important as a pollution free environment and at this stage our devotion removes negative thoughts from the mind and keeps it pure.
Last but not the least when the mind is purified, our devotion guides us to think of how much we are working for the welfare of others and how useful we are to them.
