"God, who at sundry times and in divers manners spake in time past unto the fathers by the prophets, Hath in these last days spoken unto us by His Son, whom He hath appointed heir of all things, by whom also he made the worlds;" Hebrews 1:1-2
No one should question that God has chosen many ways over many centuries to reach the hearts of men. We need not argue about who God spoke to or how that person received their inspiration. We would be guessing. But, "in these last days," those who are hearing from God are hearing from Christ, through the indwelling Holy Spirit.
If you are seeking a deeper walk and more knowledge and wisdom, simply heed the words of Jesus. The highest level of enlightenment is finding, listening to and following the Son of God. There is nothing even comes in a close second. Seeking and dabbling a little here and a little there will gain you worldly insight, but when you have a real need that needs a real God, you won't be praying to Buddha or Vishnu or Mohammad or Allah.
You need not find fault with these men or those who follow them. Every journey deserves respect. But for you, has God called you to follow men, spiritual leaders or figure heads, or has God called you to follow the Son of God?
It's time to make up your mind.
