"tómalo" and "tómatelo"
What is the difference between "tómalo" and "tómatelo"?
Also, i have heard both "descansa" and " descansate" are correct. Any other examples? what's the difference?
Why does having a "te" change its meaning?
how do i know when i need to use "te" and when not?

When the verb is not reflexive we can add a personal pronoun to create emphasis. The translations into English will vary depending on the verb, but the additional personal pronoun indicates who is affected by the action.
Tómalo .... Take it
Tómatelo ... Take it with you
In the case of "descansar", this verb is mostly used as intrancient, so it can be used with or without the personal pronoun, which just makes it more personal.
"toma" is the imperative form of the verb tomar.
"te" is a pronoun for a complement without preposition of the second person singular (tú).
Therefore, toma or tómate are similar in meaning.
"lo" is a pronoun for the direct object (for a masculine, singular noun)
Therefore, tómalo or tómatelo are the corresponding forms of toma + lo or tómate + lo.
Regarding "descánsate" This is a reflexive usage, "Relax yourself."
"tómalo" is used when you say that someone can grab something. "Me prestas tu libro, claro, tómalo de mi mochila". "tómatelo" is used as an order, a command. "No quiero tomar mi medicina madre, cállate y tómatela"
Tenga cuidado no confundirlo con la tomatillo desde Ecuador..
Be careful not to confuse it with the tomatillo from Ecuador.

"You say you don't like it. You say you haven't tried it. Taste it, will ya."
"Taste it, will ya". I think that's the essence of "Tómatelo (la)". Now, that is emphasis.
