Saints with realized soul are very rare in this world. It is really a very difficult task to write their life sketch. They look like any ordinary person but are internally merged with the super cosmic energy. An ordinary person as mentioned in Gurbani cannot describe their spiritual experiences.Only realized soul can understand about another super soul.
The best way of spiritual development for people with social commitment is sacred music.It produces a kind of detachment in the midst of family life.The Gurus regarded kirtan as particularly suitable to the household's way of life.Guru Arjan says: "He who day and night chants kirtan remains detached in his household."
Kirtan makes one fall more in love with the Gurshabad. Try doing kirtan with sincerity and emotion then do nitnem or any paath rite afterwards and see the difference for yourself. Even if you dont know how to do kirtan on the vaja you should still do it with your heart or mind as this too still counts. Also going to sangat and singing and listening to kirtan is of paramount benefit. Without these acts the seeker does not reach far in Bhagti. You dont need to be a musician or have a perfect voice to do kirtan all you need is a heart and devotion. The more practice of kirtan the more devotion we build up.
