Thinking about guru or loving him from within is essential as that mechanism actually generates vibes between your soul and of the Guru who is the cosmic self. It is the short cut process to quickly receive the cosmic energies. Those energies would be quite useful in your day to day life.

If you can learn Guru Astakam mentioned here in this video, it would be great. You can also understand the meaning of its lyrics too.

You need to make efforts to write down its lyrics, learn the correct pronunciation and then learn it. If you can learn that, the process of learning would take few days and in that process, you will literally start merging with the Guru (which is the objective of this whole exercise). However, there is no force to do it, as part of the path, it is given here, which you can follow or not follow at your interests.

If you are not Indian and from other countries, it would be quite difficult for you to learn. So for those who are not from India or those who cannot do such long exercise mentioned above. They can at least chant

Guru Brahma, Guru Vishnu, Guru Devo Maheswaraha

Guru Sakshat Parabrahma tasmai shree gurave namaha  .

If you cant chant this as well, you can even say within these words in your own mother tongue – “Guru is Brahma, Guru is Vishnu and Guru is Mahesha. Guru truly is God. I bow to the Guru”. You can say these words in your mind (in your own language). You can say this way at least for 12 times a day either in morning or evening, so you create such vibration.
