The art of wisely relating to life and heightening the spirit is being spiritual. [……]
To live a life of gratitude is an enlightened way of living. Be grateful and not greedy. If one is grateful, one is sensitive to life; if not, one is sentimental. Being grateful, one will not be egoistic and being sentimental, one becomes egoistic. Drop the arrogant self to be truly spiritual.
– Swami Sukhabodhananda
