cults of worship of tzadikim

The most important thing in the Torah is not to do idolatry.  How things are in the wider world others will have to answer for. But in the Jewish world the cults of worship of tzadikim are great and many.
And we know from the sages of the Talmud, כל הכופר בעבודה זרה כאילו שהוא מודה בכל התורה כולה Anyone who denies idolatry is as if he admitted the truth of the entire Torah

The way this was brought home to me originally was by reading the Old Testament when I was in Tzefat (Safed) in Israel.That is if you just start at the beginning and go through the whole thing you will see the one thing the prophets are always upset about is idolatry.

At a later date, I was going through the book of Daniel, and there it was clear that Daniel and this friends were praying to God directly. Not through anyone, nor in the merit of anyone.

 But furthermore, I would like to ask people to be careful about this. With every ounce of my being, with every bone in my body, I ask you to stay away from the cults at all cost. This will certainly be accounted to you as a great merit of listening to the Torah.

After that we have come to this, then I was thinking about the next step of learning the whole Torah in order to keep it. But first things first.

That is I was thinking of a small program of learning through the entire Oral Law  by just devoting a 40 min. to it daily.

Because that is all it takes in order to get though a 1/2 page of Gemara, Rashi, Tosphot, Mahrasha and Maharam from Lublin. Then you could continue through the Jerusalem Talmud, etc. until you have finished all the sefarim of the Chazal.
