You cannot preach without making your life first of all perfect. If I remain imperfect, I cannot preach. One must be perfect. That is not very difficult. We have got direction of great sages and saintly persons and God, Kṛṣṇa, Himself. So to make our life perfect is not at all difficult. We are simply neglecting. That is our misfortune. Mandāḥ sumanda-matayo manda-bhāgyāḥ (SB 1.1.10).
Because we are manda, manda-mataḥ, we are accept some bogus logic, bogus "ism," and wasting our time. We should take from the śāstra the real path. Then we shall become intelligent. Su-medhasaḥ. Yajñaiḥ saṅkīrtana-prāyair yajanti hi su-medhasaḥ (SB 11.5.32). The short-cut method. Intelligent class of men will take this saṅkīrtana movement for his spiritual elevation of life. It is a fact. It is scientific. It is authorized.
So don't neglect. Take this chanting of Hare Kṛṣṇa heart and soul, and anywhere . . . niyamitaḥ smaraṇe na kālaḥ. There is no rules and regulation that, "You have to chant at this time or that time, in this position or that position." No. Because it is especially meant for these fallen conditioned soul, there is no hard-and-fast rule.
