We have ears, tongue and eyes among gnanendriyas most powerful knowledge providers with which there will be lot of internal disturbances.
We should not listen through “EARS”, which is not related to us or for which we are neither responsible nor answerable. Unnecessary inflow of information from this indriya generates unwarranted garbage in our astral body. This should therefore be controlled.
Next gnanendriya is “TONGUE”. Through this we become slave to taste and take unnecessary food. This in one way results in indigestion and also other diseases like diabetics. So we should have control on tongue.
Further powerful and dangerous gnanendriya is “EYES”. No doubt through this indriya we see world around us, but we also see unwanted items and create unwarranted desires. So friends eyes, tongue and ear are most dangerous gnanendriyas which require control.
Now, there is another karmendriya which is also equally dangerous. It is speech generated through tongue. Through “TALK” we either to good deeds or bad deeds. So we should be careful with this karmendriya also.
We have a commander-in-chief of indriyas. He is “MIND” . If one can control this, he can even become Almighty. Entire spiritual practices are basically aimed at controlling mind. People generally think that “indriya nigraha” (control of indriyas) is important sadhana. But it is not so. What is required is realisation
oriented attitude towards subject matter of indriyas. In Bhagavad Geeta in second chapter, Lord emphasized that any interest on subject matter of five elements (sound, touch, form, taste and smell are subject matters) converts interest as desire. If desire is fulfilled then thought for repetition is generated. If desire is not fulfilled angry will raise. With angry, person looses senses and losses control on himself. So realization oriented knowledge referred above should help us in removing interest on subject matter of five elements. To do this, we should divert our interest on some better aspects. Like doing “NAMA SMARANA ” or uttering “MANTRA” or doing meditation. Let our sadhana start on any of these points.
