The next level is when you take the time to regularly consider all of the good things in your life: family, friends, health, your home, your favorite things etc. This is good, as it is a bit more proactive; making this a habit through a practice such as writing a daily gratitude list has become very popular.
The next deeper level is when you are willing to try and be grateful for all things in your life-both bad and good. The ill health that make you appreciate your usual good health. The death in the family that shocked you and makes you grateful for the family that you do have. The failures, pains and frustrations that can lead to character growth and development. This is a lot more difficult to do, and it can be easy to lose sight of our ability to do this, and retreat back to level 2, when we just want our favorite things, and nice experiences with good people, and when we do not get these, we are no longer appreciative.
Then there is another, much deeper level of appreciation, where we are able to hold and trust that no matters what happens, we will be appreciative; for we knew that there are meanings, purposes and connections beyond what we can understand and piece together. At this point we know death is coming, so we appreciate life. We know pain is unavoidable, so we endure it patiently, knowing it will end. We experience disappointments, break ups and set backs, and yet our appreciation remains a source of strength for us throughout. We appreciate absolutely all that we have and all that we are, for we now know that we cannot hope to understand the true meaning or purpose of everything, and that’s ok. Instead, we are grateful for whatever comes: for all leads to growth, experience, and all is an equally valid part of life. Acceptance with no judgement is a part of our appreciation at this level. We no longer just expect life to give us nice experiences, there is much more deeper activity going on under the surface than that.
