There are several ways in which the Truth can be communicated to the seeker. For those of you who are new to the teachings of Advaita Vedanta, it may perhaps be beneficial to familiarize yourself with them before trying to understand the matter being discussed below. While it is absolutely true that no practice or sadhana is really necessary for Self Realization, for most of the seekers, a level of mental preparedness is essential to grasp the pointers to the Truth. There are several methods to improve the one pointedness or focus of the mind on only one object so as to filter out all unnecessary distractions for the mind. This one pointedness or determination of the mind is essential for the arrow of the pointer to strike the target. These methods would again depend on the nature of the mind of the seeker and level of maturity of the seeker. The methods include prayer, meditation, chanting (japa) or breath control (pranayama). It is beyond the scope of today's discussion to address all these methods and the reader is advised to inquire about the same in the many exhaustive works of Vedanta already available.
This discussion is regarding the pointers from the Guru when the seeker asks the Guru about the Ultimate Truth. This is true of seekers who have perhaps already exhausted all other avenues of reaching the Ultimate goal and have come to the Guru in desperation and hope to be finally liberated. Generally, depending on the level of maturity of the mind of the seeker, the Jnani (Realized one) will try to point him/her to the Truth. The Jnani can know, based on the questions that the seeker asks as well as the responses or answers to questions from the seeker, as to the level of maturity of the seeker. There are basically two methods of communication in this world. One is through the medium of silence and the other is through the medium of language and words or gestures, and the second is through silence. For most of you readers, the first method may seem a bit strange as to be even mentioned. Since, we are addressing this matter in the state of duality, remember that opposites or dyads are the nature of duality. What is silence without sound and what is sound without silence?
The Guru/ Jnani may decide to convey the message through silence or the look of Grace. Bhagawan Ramana Maharshi is a well known for using this method of conveying the Truth. It is a powerful method with immediate results for the mature seeker who is ready. To give an analogy, if the wood is dry and ready, a spark is all it takes for it to burn immediately. On the other hand, if the wood is only partially dry, it takes a little while for it to catch the fire and may need several attempts to light it. A wood that is still wet, will need more time for it to dry before the spark can even attempt to get it to burn. In the same way, the state of mind will determine if the pointer from the Guru will achieve immediate results or if more time is needed. In the method of silence, all it needs is for the Guru to look into the eyes of the seeker and the seeker is no more. The seeker becomes one with the Guru and the message gets through.
The other method of communication is through the medium of words or language. Since most seekers are immersed in this state of duality and language is the medium of duality (the speaker and the listener), this method is likely to work for the majority. Shree Nisargadatta Maharaj is an example of a Jnani who exploited this method of communication. After all, it does not matter how the message gets through to the seeker, the goal of the Guru is to make sure that it gets through. Even if the message from the Guru does not light the fire right away, in due course of time it will. The words of the Guru will never go to waste on the ears of a sincere and determined seeker. It is just a matter of time before the seed shall sprout, as the Maharaj used to say.
