A Spiritual Guru has five important qualities:
1. Practice what you preach:
Vethathiri Maharishi practiced what he preached.
He did the exercises, kayakalpa yoga, meditation, introspection and observed silence regularly.
When you look up to a teacher like him, you are truly inspired.
He lived by example.
That's the kind of teacher we must aspire to be.
2. Thoughts, words and actions are in sync:
A person whose thought, words and actions are in sync is a high integrity person.
A spiritual guru will not speak, act or think in a way that might bring hurt to another. His life will be spent on removing hurts from within and without for himself and others.
4. Harmony in relationship:
A guru who is worthy of our respect and following is someone whose relationship with everyone around is in complete harmony.
A person who has spent enough time in silence introspecting would understand that he is only a fraction of the divine force.
