Srimad Bhagavatham (10:14:8)
भुञ्जान एवात्म-कृतं विपाकम्
हृद्-वाग्-वपुर्भिर् विदधन् नमस् ते
जीवेत यो मुक्ति-पदे स दाय-भाक्
Brahma sings "Lord, one who spends his life praying and looking forward to Your Grace, quietly experiencing the joys and sorrows which are visited on him as a result of past actions (Prarabdha), and prostrating to you with heart, speech and body, becomes ultimately entitled to liberation (Mukti)''.
So, this is actually a three-in-one Sadhana
(I) incessant prayer for the Lord's Grace;
(2) quietly experiencing Prarabdha-caused joys and sorrows; and
(3) prostrating to the Lord with heart, speech and body.
One should always weep and pray for the Lord's Grace. Why not take the succor of the Lord Himself for attaining Him? One should not rebel against the sorrows and miseries of life, which are only a result of one's own earlier actions. These are meant to purify our mind. Full acceptance of the Lord's will and bearing all calamities cheerfully is itself a Sadhana. Remembering the Lord continuously; surrendering the mind, speech and body to him; performing only selfless acts beneficial to mankind; contemplating on the Lord continuously; and either resorting to silence or surrendering one's speech to the Lord, or, if need be, using speech only to chant the names and glories of the Lord, are sure means for realising the spiritual goal.
