What is the best period in man's life to start sadhana ?
Start today the sadhana that has to be done tomorrow. Start now the sadhana that has to be done today. One does not know what is in store next moment; therefore, there should be no delay in engaging oneself in the sadhana that has to be done. Physical stamina is also necessary for this sadhana, and so, the body has to be tended, though over tending causes damage. (Prema Vahini, pg 69)
