In samadhi, one is in a total state of meditative absorption and the 
need to meditate, in certain cases, no longer exits. But this varies 
from person to person, and from system to system. Ramana Maharishi, for 
example, it is said, just continued in a deep state  of samadhi for his 
entire life. Swami Sivanada, continued to practice all the Yogas until 
his death or mahasamadhi. My own teacher, Lama Geshe Damchon Yenten, now
 85, and a Gelugpa Lama (the same lineage as the Delai Lama. Gelugpa 
meaning the  celibate lineage. The same as bramacharaya In Hinduism.) My
 Lama still meditates every day so as to attain Total  Realization or 
Buddha- hood, even though he already in a total state of samadhi
.
Finally, the method I follow is the Tibetan Buddhist system of Dzogchen, of the Ningma lineage or "ancient" ones. Made famous in modern times by Lama Namhkai Norbu. Here one simply rests or relaxes in one's Understanding. One meditates for short periods during the day, identifies with one's True Nature, the Atman and then one simply relaxes in one's understanding. One can continue to do mantras, Bhakti Yoga, or any practice but the most important tool in this system is total Relaxation in the understanding of who we are. Not the jiva-atman or ego, but the Higher Self . That is the Atman and finally, the Cosmic Consciousness, Brahman.
