Gurudeva and his mission of Bhakti-yoga
The original guru is God Himself. Teaching, through his own example, how the living entities can serve to the Lord, the guru is the personification of service attitude to the Supreme Lord. Bonafide gurus are always very tolerant, merciful, friendly with all the living entities, have no enemies and are always very peaceful. Their hearts pain seeing the suffering of others, so, for this reason, they go to many different places of the world in mission. Their sole purpose is to enlighten everyone about the true nature of the soul and the true meaning of life.
Who am I? Why have I come to this material world? Where will I go after my death? — All human beings worthy of being called humans, at one point come to this stage of existence where they inquire about the soul and about God. — What is the difference between life and death? Is there anyone who really cares for me in this world?
Forgetful of our own constitutional position, we all, living entities, wander in the cycle of repeated birth and death. In this cycle, we obtain a different body and condition of life according to our previous activities (our karma).
When the soul develops a transcendental love for the Supreme Lord, he attains the complete self-realization. At this point, the soul delivers from this material world and from the cycle of birth and death and finally goes to the transcendental world, the abode of the Supreme Lord, also known as Vaikuntha-dhama or Goloka Vrndavana.
Actually, to perform loving service to God is the original nature of all the living entities. This is called Bhakti-yoga. Yoga means to unite; to unite the soul with the Supersoul (God), and bhakti means devotional service.
The best way to connect to Lord is through love, as Lord Krishna (God) Himself told in the Bhagavad-Gita (6.47), which is one of the most important sacred religious texts:
yoginām api sarveṣāṁ mad-gatenāntar-ātmanā
śraddhāvān bhajate yo māṁ sa me yuktatamo mataḥ
“And of all yogīs, he who always abides in Me with great faith, worshipping Me in transcendental loving service, is most intimately united with Me in yoga and is the highest of all.”
This message of Bhakti-yoga, this message of Love to God is the message that, in essence, all the religions carry. After all, as the Bible says, God is Love and Love is God and God is the embodiment of Divine Love.
