Being spiritual means being connected to the self. You don’t have to look for outer motivation and clarification when you are spiritual, the motivation comes from within your conscious. People practice spirituality in a lot of ways. Some do it by themselves and some practice it with the help of spiritual gurus and saints.
One of my personal favorite spiritual guru is Sadhguru. He is an Indian yoga guru and has also authored several books considering various subjects.
He doesn’t tell the listener to perform a set of tasks, doesn’t read religious literature in front of them nor gives them motivation by chanting mantras. Instead, he delivers in his speeches, the stories of inspiring personalities which automatically inspire the listener to be spiritual.
He creates a path on which one can walk and move towards spirituality on his own. Unlike other self-proclaimed gurus, he doesn’t create any void between your thinking and his thinking. Instead, he fills the void between your self-realization and your consciousness to help you motivate.
All these practices automatically make you spiritual. He explains in his lessons that spirituality need not be practiced through any book or literature. Instead, it comes from within, directing you to your inner self. Without any propaganda, he is the best spiritual guru in India.
