Why would Hindu's study Jesus and believe Him to be an "Avatar" when He claims to be the only way to God (John 14:16)? Hindu's believe in the "way of works," which is salvation (escape) through good works (or adherence to Hindu teaching/scripture). Jesus teaches salvation through faith in Him and did not call for us to be legalistic.
Here is how I would interpret John 14. (Hinduism has sooo many different sects and philosophies it is hard to distinguish between them, I consider myself a Hindu and a Christian, but most importantly, a Devotee of God).
1Let not your heart be troubled: ye believe in God, believe also in me.
Believe in God, the all powerful creator, and His earthly manifestation as Jesus the man, who embodied the Cosmic Christ, the only begottoen manifestation of the Uncreated Creator. The Christ (The All Powerful, All Loving Force), embodied as Jesus, is in us all. We have to access it through prayer metiation, and devotion.
2 In my Father's house are many mansions: if it were not so, I would have told you. I go to prepare a place for you.
3And if I go and prepare a place for you, I will come again, and receive you unto myself; that where I am, there ye may be also.
Jesus is urging us to follow his path as a way-shower, being Divine in human flesh, he is encouraging his disciples to raise their conciousness and assures them that there will be a place for them in the astral realms to commune with God.
4 And whither I go ye know, and the way ye know.
5 Thomas saith unto him, Lord, we know not whither thou goest; and how can we know the way?
Here Thomas is like "wtf, ummm, I don't know the way" and Jesus drops the next verse on him, basically saying "Haven't you been watching me, haven't I taught you as my disciple?"
6 Jesus saith unto him, I am the way, the truth, and the life: no man cometh unto the Father, but by me.
No one can reach moksha, liberation, "heaven" as you might put it, without uniting themselves with the Christ Spirit (again the only begotten manifestation of the Uncreated Creator) Dropping egoic attachments, remaining devotional, moral, and communing with God, Jesus is using the example of His Way, Truth, and Life to tell his disciples they must not only believe in him, but become like him. No man reaches liberation without uniting themselves to Christ, not a human manifestation of it. He is speaking of Who He Is, not a belief in him. The Blessed Son of God speaks extremely deeply (and the Book of St. John is perhaps the deepest), not in kindergarten-esque oversimplifications.
7 If ye had known me, ye should have known my Father also: and from henceforth ye know him, and have seen him.
Again saying, "If you would have been watching me and seeing the Divine Radience busting forth from within Me, connect with it, and then let it take over your heart, you will know God"
Apologies for not putting the words of Christ in bold, im on my phone.
